On the Grid : Marvel Coffee Co.

"Marvel is a recent addition to the city with two locations within a 10 minute walk of each other. And no, they are not affiliated with Marvel Comics or Studios so don't expect Avengers or X-Men crashing through the place at any given moment. Coffee is sourced globally with beans from various regions in the world and sandwiches and sweets locally, either in house or from places like Sweet Flower and Cinq. The aesthetic of white marble, greys and a polished look work to complete the feel of an upscale cafe away from the Starbucks of the world." - Kev Seto

Tried the spanish latte and it was delicious! The cafe is very small, not much seating inside. There is a corner area that could seat 2 with one table; bar area thar has one stool and then a bench area with one table… the bench could prob fit 4-5ppl. I didnt see prices for their pastries, but there were also a very small selection when i got there. Quaint little coffee shop that is otherwise hidden, def worth a stop, but maybe grab and go.

Conflicted about this cafe. Been living in the area for a few years and typically will stop by Saturday/Sunday mornings before the gym. Haven’t had the baked goods before though they do look quite fresh/tasty. Coffee itself is decent, not the best but definitely not the worst. Cute atmosphere inside and the patio is lovely in the summer. I’ve found the service quite poor though, especially when you’re paying $6.50+ (all in) for a cortado. Without fail every time I visit the staff seem thoroughly uninterested and as though you’re a burden for them. Somehow that’s been the case regardless of the staff over the past several years. I always try to be polite and cordial, and though I’m not expecting silver spoon service, some minor reciprocation would be welcome. I frequent most of the cafes in the area and for some reason this is the only one where the staff have a consistently negative attitude.

I am a simple girl. I drink my coffee black and love it strong albeit also a coffee purist. I visited this place yesterday for the first time and all I can say is WOW!!!!! The coffee quality is the best I have had in a long time (and I have tried a lot). I want my coffee to do what I need it to do in terms of caffeine and in addition to the tasty notes, this coffee DEFINITELY does what it is suppose to do. Will be back repeatedly.

I’m not a coffee drinker but I love hot chocolate & I’m always on the hunt for places that don’t use powder full of sugar & preservatives. Mercury makes their own hot chocolate mix in house made from real chocolate! The barista showed me the container and explained the process they take to make it. Well, it was lovely! I went back the next day & had another. Milk is never hot enough for me so I always get it extra hot. A little sprinkle of cinnamon on the top & extra yum! My friend got a flat white & said it was great so to us this place is a win for coffee drinkers & definitely a win for hot chocolate lovers! I also tried a cheese croissant which I had later in the day and it was delicious. Flaky on the outside soft on the inside. Next time I’ll try their chocolate one! *** came on to update my service rating. I took away a couple stars because I went back with my small dog (6 pounds) and I barely got in the door before the barista shouted at me “dogs are not allowed in here”. No question as to whether he was a service dog, no gentle hello sorry but dogs aren’t welcome here… they were just so rude and frankly it was super embarrassing. I loved this place but was so disappointed in how rude I was treated. My dog is actually an esa however despite that I have no problem not bringing him in somewhere he is not welcome. I could have missed the sign on the door but even still, there are many ways to tell someone their dog is not allowed other than being rude about it.

Almost 8 dollars for the most average almond milk vanilla latte ! I go back to the coffee shop to ask if any vanilla was added and she lets me know that only 1 pump gets added for 50c lol she made me a fresh one where I could actually taste the sweetness. Not a great attitude from her !

Ethiopian blend (espresso) is an extra $1 - no biggie. Fast wifi and a/c. Couches are beautifully comfortable Floors and couches are not being vacuumed as much as necessary so I would suggest a grab and go unless you want bugs crawling on you while you are have your morning coffee. I'll be back to get out of the heat but can someone please call the owner who is a more regular customer. First time here for years.

My first impression of this coffee shop was the simplicity of it, there is a very open space, some couches and a table to sit at, and lots of natural lighting coming into the shop. My partner and I came to this shop for some cold brew ($4 each). I got the regular cold brew and he got a coconut infused cold brew. We both liked our drinks very much. The barista girl that served us was very energetic and kind, she gave us a little run down of their menu and cold drinks as it was our first time here, even explained to us how they make their cold brew. She told us that their cold brews are made over 14 hours through the glass drip (shown in one of my photos), so catch them earlier during the day because they may run out! Coconut cold brew, was good it has a light coconut water flavour in it, perhaps they used coconut water just for that, it doesn't taste like it had any artificial flavour.

Americano was fine, kind of bitter and the cup was nowhere near full. Found the employees to be rather short and unfriendly. Could have just been a busy day.

I was not impressed, but I know this place always has good reviews. One thing I am surprised at is that customers who come here are very fancy and good looking so as baristas. I do not think this is a fancy place, but people are fancy and stylish. Coffee was not cheap. They gave me old coffee from the pot, so the taste was sour. The bathroom was not clean. They are selling nice paintings. Probably it is very good place for locals.

Horrible service...... absolutely terrible service. However.........their coffee more than makes up for the terrible service. This place has skilled passionate staff that knows and cares about coffee!!!! They just don't smile, so if you're looking for Starbucks friendliness then this isn't your spot.

I really feel for the friendly guys that work inside Mercury Espresso Bar! It was so hot and stuffy inside. I was sweating while sipping my Cappuccino ($3.50) with no air conditioning or fans.... I ended up taking refuge on their outdoor patio. Luckily their wifi signal was strong enough, so I have no problem uploading my photos using my Yelp App. I wish there are more electronic outlets, as my phone was almost dead and in great need of charging..... Cappuccino was A-OK! But the things that impressed me the most are the friendly staffs... I will be back!

Solid coffee near Urban Post in Toronto. Americano and regular coffee are solid, well brewed and delicious. Our regular during color correction. There's a ton of coffee spots along Queen St here and this is a solid cup to go.

For 3 years this was my fav shop in Leslieville, but the Barista quality has been so inconsistent that I won't be back.... and It's not the beans, Cut Coffee is great! Mercury used to be one of the best now I'm sorry to say that if you want consistency you will need to go to Boxcar Social, Te Aro, Rooster or Buds (run by a former Mercury employee). Dark Horse's consistency is gone too, so don't go there either. Only 4 years ago in Toronto a $3.50 coffee used to be made by baristas that loved their craft, now that's become the normalized price for an espresso based drink and with that mentality the quality and consistency has been lost by Mercury. It's sad, because I loved Mercury for 3 years and through 2 owners who were usually at the shop training staff and maintaining quality control that's no longer the case.

As I walked know, I asked the person at the cash if their espresso was old school nutty tasting or fruity and the person didn't really seem to know. After consulting with the barista, I've been told old school. I was quite excited until I took a sip of the cappuccino...definitely on the fruity side. Although not bas coffee, just not what I personally like. The shop actually looks pretty nice but a bug hot inside. I like the fact that they have a terrace on the side of the building.

The non-coffee offerings at Mercury are quite uninspired. I gave 'em back my chai because it tasted like water with a hint of cinnamon and nutmeg. It was replaced by a decent enough hot chocolate. But hey, it's an espresso bar so I can't fault these dudes for much, especially given their exceptional soundtrack which featured some of my favorite early 90's dance hits on my last visit.

As a die-hard coffee snob and unashamed starving artist, I discovered well over 10 years ago that coffee-houses would send me to the poor house. Even including milk, beans, grinders, cups, and high-end Italian espresso machines between my wife and myself we have saved in excess of $25,000 by NOT buying our coffee while out on the town every day. (2 lattes * 7 days a week * 52 weeks a year * 10+ years = ouch!) That being said, if I do find myself in the area, I can't help myself and walk in to have a latte. Not only is it delicious, they have free wi-fi (ask for the password du jour) and the barristas are highly skilled. They still use a proper "semi-automatic" machine where the barrista has to be skilled in the preparation of the ground coffee. (Starbucks switched to "1-touch" super-automatic machines a few years ago). If the barrista's touch is off then you can get a ruined shot... which I've never seen them do. They do have a small selection of pastries but I just come for the beautiful coffee. NB: they apply a dash of cinnamon to the espresso before pouring the milk. This helps richen up the colour of the crema (brown foam on top of espresso) giving the barrista more contrast to work the latte-art. This place will be one of the few places that can make a coffee even the most die-hard coffee snobs like myself can enjoy.

Worst service ever, waited in line for almost 10 minutes, got inside and guy says sorry not taking any more orders. We were literally the last in line and he just said no. Never be back again, pretty pathetic when trying to support small businesses.

This cafe caught my eye with it's character. The sign on the window misleads an unobservant passer by offering "Leather Jackets and Sporting goods" This original sign was revealed and then salvaged by the art appreciative owner of Mercury Espresso. Organic and Fair Trade, this eclectic cafe has and individual feel to it while offering a good quality product. Chairs and tables at the side to sit and pause. Good Cappuccino, nice staff.

Second spot on the "Kat F - Miss U Crawl" is a place that Kat F. even put her mark on the door. They have a "People LOVE Us on Yelp" sticker on the right door. Look up at the ceiling and notice that they have lights that are probably designed so it's representative of some Solar System. The lights at the counter are made of Kitchen Sinks and like most other Cafes, they have paintings by someone hanging from the wall. Cappuccino($3.25) was the beverage of choice, however at this time I have to say it's not one of my favourite. It was still nicely Crema'ed but you'll notice the larger bubbles all around the top. Another thing is that it had more bitter/sour taste than what I wanted, but I won't take points off from this as I had a Sweet Pie just seconds before this drink. They do have a smallish outdoor seating area.

One of the best cappuccino/Americano. I have been coming back here more than five years and, every time I visited, it consistently tastes amazing; not too bitter, not too sour, that is exactly how I like!

I've been remiss in not reviewing Mercury. I found them early on and was readily taken with their quality espresso (Intelligentsia beans) and the groovy, repurposed-building (an auto garage, maybe?) style atmosphere. Like Kat F. noted in her review, they had a cool selection of music on hand. My girlfriend had a latte which she quickly slurped up (in noted contrast to the ones I make her at home, peeving me somewhat, ahem) and I remember my cookie being pretty tasty, too. I'd be a frequent customer if only I lived in that neighbourhood. Of note, I recently had the opportunity to take a "Barista Training Academy" session, hosted at Mercury (at their sister location) and given by one of the co-owners (Matt, I think). It was lots of fun to my coffeegeek sensibilities, and I got to see first hand Mercury's dedication to making a quality beverage. They are definitely part of the so-called 3rd wave of coffee, and deserve to be on your tour of quality coffee bars.

3.5 Stars I came to Mercury a number of years ago and was completely turned off by the atmosphere of the place; it just didn't fit my vibe. By the advice of my friend (and best barista in Toronto, in my opinion) I came back to give it another go. The atmosphere is still the same I find. There is nothing wrong with it, but I just don't like the vibe personally. The coffee is good. They have at least one good roaster they sell in Phil and Sebastian and do it well. I just find this place is just a little behind the curve in terms of developing and trying out new things with coffee. For example, cold brew. There are different styles of it, but these guys are just getting it going here. Other places have had it for years. There is nothing wrong with this place at all. It just seems like they are not the innovators that other shops are. It's not bad, but I will not be back. I do wish Mercury all the best! That's it.

Super friendly, lots of energy... Must be all that perfectly pulled espresso. Cortado was very awesome. Chocolate chip cookie was pretty good. Decaf Americano was kinda bad, but it's very rare to find a good decaf so they're forgiven. They said it was the best decaf espresso in the city... I can't say I've tried another but if that's the best then that's a sad state of affairs for decaf espresso. I love the taste of espresso, I just don't want to get jittery if I stay for more than one drink. Atmosphere is not the most conducive to working because the unrecognizable (by me) music is a bit loud and people are talking above it, and when the sun set it got extremely cold, but their wifi is fast and reliable. I didn't see any outlets but I didn't stay long enough to need one. I must repeat that their cortado was amazing. It was extremely delicious and one of the top ones I've had. Cortado or flat white and a chocolate chip cookie is my favourite combo and these people did it right. If you want tasty espresso based drinks, here's a great spot. I'll definitely be back (but not when it's too cold out). They're friendly and the espresso is delicious. The atmosphere may not be as nice as the nearby Dark Horse but I prefer this place because they have better cookies.

This is a real old school joint. It has that slightly soap-box feel of a "animal free" joint, even though thy serve milk. To say it's a diner is not entirely true, it's more of the old school cafe type deal. It's not very big at all, and they have the minimal cafe sandwich board options, but they make a really mean cappuccino or latte and they have soy milk, which means they're aces with me.

This Leslieville local is a big ol' room that smells like sweet, sweet coffee. It's like a cube of caffeine. Their brewed coffee (pressed actually) is in their own words, "not terrible" so I'd suggest an espresso instead. It's in their name after all -- and they do it very well. I've had a few of the espressos but my favourite is the cortado. On one occasion they made and remade it while I watched in rapt attention as they try to get the pour perfect. Though this might seem amateurish, it's far from that; they just really give a shit about serving a solid coffee. Plus, it's fun to observe what's going on behind the scenes. Though they have free Wifi (the password is on a George Bush playing card) this is more of a chill spot than a work spot. Outlets are hard to find, the music is pretty loud, and the layout isn't too conducive to productivity. But if you want to killer coffee in Leslieville, go here. Do not delay. Obligatory Title Pun: MERCURY will get a RISE outta you. Menu Readability: Two large chalkboards with childlike printing. Need to mention: Everyone who works here has facial hair. Is this a rule or something? What this place teaches me about myself: I can't get enough of the sound of a steaming wand.

I can't even handle how bad the service is at this place. I never go in because I know I'm going to leave feeling bad about myself - but today I was in a hurry and it was right there. When I ordered my drink there were 2 guys ahead of me in line, 3 behind me, and 2 working. I got my drink dead last, and when I said thank you I got a "yup" in return. Maybe if the two staff hadn't been reminiscing about the various albums they had listened to throughout the course of the morning (seriously?) they could have focused on serving customers. Oh no wait, they served all the dudes, they just ignored me. If my Americano wasn't so good I would have given this sorry joint 1 star.

For those who love coffee, perhaps a little too much (hee hee), Mercury Espresso Bar is one of Toronto's main go-to cafes for the best of that liquid black magic. I think what makes Mercury such a hit with coffee drinkers is that not only are their baristas knowledgeable about the coffee they serve and quite skilled at pulling espresso shots or getting the Chemex brewed just right, but also that the owners are hardcore coffee geeks who are always on the hunt for the tastiest roasted coffee beans. In fact, just recently Mercury switched from Intelligentsia coffee, considered one of the best suppliers of roasted coffees in the world, to Terroir Coffee located in Acton, Massachusetts simply because the owners felt the beans superior. Any which way, the customer stands to win with a yummy cup of coffee. Not only, they welcome customer feedback so that they can fine tune their offerings. Prices are on par with other indie coffee houses. The establishment is small but cozy and unpretentious. Staff are friendly and enthusiastic. I will knock'm a half star though for not having any regular brewed coffee available for take out past 4PM (they're open till 8PM). With considerable competition in the area Mercury still stands out and I recommend you dropping by. 4 1/2 stars.

Buyer beware... if you are not a coffee hipster you likely will have a pretty ugly experience. So if you are not a COFFEE Snob and one of the "DUDES" like behind the "BAR" expect unexceptional, surly, better than thou service. If you don't want an ESPRESSO beware of anything else they might serve... Today a plunger with a bit of cream in it totally curdled not the cream but the coffee... the "BARISTA'S" explanation... the coffee is too citrus and I the paying customer should never have put cream in their exceptional product. My question why did you make the plunger in the first place??? The whole experience simply left a gross feeling... and to boot the server "DUDE" didn't even offer me my money back. OH WELL There are many many more places along the street. I will enjoy the sunshine in the park with a take out from 7 or 8 other places... This version of a coffee shop would do far better on the west side of Queen...

The eternal debate among Leslievilleans is where to go for their coffee - Mercury or Te Aro Roasted? The little grungy guy or the spacious giant with fresh roast in your face? Being exposed to loud indie music, or trusted moody pop? Random bluegrass double bass or monthly cupping seminars? Though I don't live in the area, I definitely sink a lot of coin into Leslieville. Since my life has yet to revolve around a stroller, Mercury is typically my preferred spot of the two, despite having a pretty significant stamp card at Te Aro. When my favourite barista at Crema (Yonge & Bloor) migrated to Mercury, I followed him because apparently it was one of the best placed to obsess over coffee in the city. Not that the environment or people have much to do with their espressos. The drinks at Mercury are at the top of the Toronto espresso food chain. They are the rulers of the Serengeti, so to speak. Try a cortado and you will see. It is thick and creamy with a balanced flavour that brings out the espresso but softens the bitterness. Don't let anyone tell you otherwise; Mercury is worth a visit.

Eh, I'd say this is the cafe equivalent of Ronnie's in Kensington. The staff seemed totally uninterested in actually making my americano and more interested in talking with people (who weren't me.) Look, I'm all for the discussing the merits of neck beards and ideas on how to make our skinny jeans even skinnier, but at some point I would like my coffee. The interior of this place is very unique. I liked the look, especially the paintings on the wall - I also appreciated the 'no cell phones at the counter policy.' Everything here has that retro/vintage look that hipsters get super hard for, and there is a surprising amount of seating for such a small place. The other patrons were an interesting mix of hipster, people who looked like they couldn't afford a 'coffee time' coffee and yummy mummies (nice.) There was also actually a guy there who was dressed in all black with a stack of philosophy books beside him. At $3, the americano was pretty tasty, though not the best I've ever had. I'll probably back at some point (possibly with some nietzsche and an ironic tshirt)

I am a serious espresso drinker. Mercury is an espresso bar. I ordered the eponymous drink and it was one of the highlights of my week. A nice roasted initial sip that ends with an amazing fruity aftertaste. Perfection. After I finished my drink, I went up to the barista and thanked him for sharing his craft. He thanked me for making his day. Trust me, the pleasure really was mine.

This is my five star coffee place. I started this review 3 months ago and that's all I wrote. The good: - 1% feature cappuccino - the coffee - the staff - the anal leakage cartoons The bad: - the undesirable presentation of the food I always think about buying.. but never ever do - the failure of a nuitBlanche coffee snow cone ferris wheel (fail again. almost -1 star for that but... I did start this review 3 months ago and it's not like I would have logged in to update it if it were already posted.) I will go here again. You can probably cross paths with me here.

As I meandered around Leslieville, I realized that there was absolutely no shortage of espresso bars. I'm not exactly sure what it was that enticed me about this shop, but my friend and I decided to go on in and give it a shot. With absolutely no preconceived notions about the quality of this cafe, I was immediately quite disappointed with the level of customer service. It wasn't necessarily that they were rude, but they just weren't that personable. Perhaps the service would be different if I were a local and/or a regular. Given that it was a rather hot day in the city, I asked the barista if any of the espresso-based beverages could be iced. The response was anything but clear, and a tad bit condescending. Anyways, I went along with an iced latte, and the quality and richness of it definitely made up for what was lacking in customer service. I think this cafe has a LOT of potential, especially given its awesome location and great selection on its menu. It's incredible how far empathy, emotional intelligence, and conversational capital can go in a cafe setting. So long as this cafe makes a concerted attempt to improve these aforementioned elements of service, I would definitely come back and try some other beverages.

In a neighbourhood with 5 very good independent coffee shops within walking distance, Mercury is my favourite. For me, it's all about the coffee, and this is where Mercury shines. My drink of choice (an Americano) comes out perfect, with a natural sweetness to it and just the right amount of crema on top. After being exposed to a daily Americano from Mercury, I found it difficult to have one from places like Starbucks again. This place truly turned me into a coffee snob. It does make a difference which person makes your drink. I find some employees at Mercury do a much better job than others. There are two things keeping this place from a 5 - first, it 's incredibly hot in there with no air conditioning. I'm told they might have it this summer, so we'll see. Nobody wants to come out sweating after going into to grab a morning coffee. Second, they made the sizes smaller. Yes, I know it's the same amount of espresso. I liked the larger cup. It allowed me to grab a large, go for a walk, and have it last for a while.

I've stopped by here for brews every now and again, but a few weeks ago decided to "dine in" and partake in a macchiato, a definite luxury for somebody who is lactose intolerant! It's really annoying when places carry soy or almond milk for coffee drinkers to pour as a milk substitute but don't offer lactose-free milk to still get that excellent foam-age for lattes, cappuchinos or what have you, but Mercury won me over by offering it for my macchiato and then making one that was totally kickass. What resulted is a happy little camper reading Michael Chabon with a rich, nutty, sweet macchiato at the low-bar table. Warning to ladies in skirts: the stools at the high-bar table are made of BURLAP and will itch you through your tights, BELIEVE ME.

This is a neighbourhood gem! The folks at Mercury know their coffee. Love love love love love their americanos. They recently changed the size though..."it's the same amount of espresso..now with less water". Either way it's definitely delish and worth visiting. It's a little cold now to use their patio - but it's definitely a crowd favourite! PS. their ginger cookies are amazing

These people take their coffee seriously. They won't even serve a macchiato, cortado or espresso in a to-go cup. You gotta drink it there, the way it should be. I'm a fan.

I'm really torn when it comes to my feelings for Mercury. On one hand, the espresso lover in me wants to rave about their place. They are true lovers of their craft and its reflected in their beverages. Whatever you decide to order, the likelihood that you will walk away with a finely crafted beverage that is incredibly delicious is very high. I'm personally a fan of their lattes and cortados, which have never disappointed me. The staff is also knowledgeable and friendly, and can generally answer any question you may have without pretensions. On the flip side; while a purveyor of fine espresso they may be, a warm and friendly atmosphere for sitting in is something I've consistently been left without. I love to sit and enjoy my espresso beverages in a nice and friendly environment, and that's often why I opt for the much more inviting Te Aro just down the street. Every time I've gone to Mercury, the music has been at an uncomfortably high level. Paired with their lack of sufficient AC in the summer months, sitting inside proves to be far more arduous than I'd like. To sum it up; if you're looking for a quality espresso to go, Mercury is a great bet. If you want a good, relaxing environment to go with, maybe head for neighboring spots Te Aro or Darkhorse.

Ironically hipster staff who haven't clued in that being ironic and hipster just ain't where it's at anymore, and with a million signs over the counter that tell customers not to use cellphones while ordering or to not lean on various objects, it projects a seriously negative energy. Srsly? Srsly.

I love their iced cappuccinos! It's the perfect blend of espresso and milk. While an iced cappuccino isn't a proper bar drink, it is delicious way to get your caffeine on a hot day. Most places make them waaaay to milky. These guys get it right! They're non-iced cappuccinos and americanos are also first-rate. It helps that they use excellent beans from kick-ass roasters like Social Coffee Company and George Howell. I also love the decor, hipster baristas and great patio, but the lack of A/C indoors and no visa make me sad.

Decent coffee but terrible customer service. As a friend and I were waiting for our coffee being prepared (no one else behind us) my friend asked what a flat white was and pointed to the menu. One of the guys (the bearded one) barely put together 3 words, something about 'you know... Australian...foam...espresso...' Nearly slammed the cups on the counter and in returned for a thanks we got - silence. No smile. He just turned his back. The two stars are for the decent coffee. Cheers!

Stumbled upon Mercury while looking for an early Sunday morning coffee. Typical small indie café type industrial vibe. Small patio and benches out front and small pastry selection. Most importantly, solid coffee! Don't think they WiFi. I will come back if I'm in the neighborhood. Recommended

The best part about Mercury espresso is being able to walk into a small sized room where you immediately get enveloped by the smell of caffeine. I think I geta contact high just walking in. And I love it. Most of the shots are pulled as double shots already, and their cops are decent sizes so your espresso doesn't get drowned in giant cups of milk. Is the first impression of being a little bit hipster with attitude (because of the highly bearded individuals behind the machine) however after talking to the guys here lies they're much too cool to even be hipster. Great site patio to enjoy your caffeinated beverages on and very reliable WiFi. Good combination of benches, leather seating, and café tables. The espresso is quite good and I have recently tried their tea as well which is very good quality. Love the setup for the the condiments we can actually get a selection of raw sugar, literature, honey and sweeteners. And they're dairy if you want to add that sort of thing is always cold and the spoon situation is never messy. But we also does a bit of caffeine alchemy where they do offer cold brew coffee which have yet to try as well as some other contraptions which look really interesting on the shelf but never seem to have the time to ask about. These people are passionate what they do and it really comes across especially the mornings when he just want a quick job. Tips, and the morning they have a wide variety of the daily papers so if you're like me and also like to get your daily news in ye olde paper format good place to stop a quick coffee and find out what was going on the world why you're sleeping. However, I find they are morning food selection a little bit limited. Prices are decent, and a great place to meet up with friends in the neighborhood.

Once again another recommendation from my brother Canadian Friend. Mercury Espresso Bar to him is what I am exactly looking for in an independent cafe. It is gritty, no frills or gimics, all coffee. It was funny because the guy in front of me ordered a dry cappuccino and was denied (I love it). People sometimes don't fully understand that when you market a product a certain way changing it can be detrimental to your business. So good on them for sticking to their guns. However it is my turn and first thing I noticed how unhappy the Barista looks and how un inviting that can be. One would assume with the quality espresso bars Te Aro, Dark Horse) and cafes around that you would at least loose the bad mood or snobbery. I decided on a shot of espresso and to my delight it was roasted by none other than George Howell Coffee Roasters (Terroir). A legend in the coffee business and proponent of all things good about coffee. I asked for the shot short and was expecting a heavy duty amount of sweetness in the cup with tonnes of body. I did get a shot but a little over extracted as the sweetness (hints of vanilla) was lost to a more burnt carmel finish. I didn't get a chance to tap into their baked goods but I was a little disappointment in the treatment of such a great espresso. Seemed the Moody Barista was not paying attention to calibration this morning. I gave it a 3 stars because the shop was great, they have a great selection of top notch coffee beans, but the skill was lacking or care for that matter. won't be back on this trip.

Been here twice now. The first time I got a cappuccino which was perfectly prepared. This morning I stopped in for a quick americano before work and the flavour of the beans is perfectly bold and sweet at the same time. They have milk alternatives such as soy if you're dairy free. Unfortunately I just had a big breakfast before leaving home or else I would have tried one of their delectable looking pastries. An excuse to come back for sure. I love sitting in the window and people watching too. The atmosphere is cozy and it is definitely better than your neighbourhood starbucks.
