Trillby & Chadwick

A fun speakeasy, once you figure out where it is! Go inside and ring the bell. The staff were really friendly and we loved the idea that the cocktail menu was also a puzzle story. The place itself is very cozy, it felt like we had slipped back in time. The cocktails were expensive but very good. You have to leave through the back.

I was really excited about going to this speakeasy bar when I found out about it existing in Helsinki. Unfortunately we had the misfortune of ordering a drink in a can because it seemed interesting, the waiter said something about it being a wildcard when we mentioned we want to get it, but we didn't expect it to be actually disgusting and undrinkable with a very intense smell, thought it would just be special. Another waiter came to ask us later if everything is ok and we told him about the drink that we can't drink because of the way it is, he asked if we want something else instead and we asked for a recommendation and he brought a new drink. But instead of replacing the drink they charged us for the replacement as well without even telling us, we found out at the end when we paid. Really disappointing experience, there are other bars that don't serve undrinkable drinks and offer better service in Helsinki, go there instead! Also, they don't want you to take pictures inside the bar for some reason

The drinks here were incredible. They are truly crafted, not just thrown together. I love gin so, I just asked him to make me something not to sweet. He came out with this AMAZING drink served out of a little bathtub. It is true that there is no sign on the door and you call from the vestibule but do not be intimidated. They were really nice and it was a fun experience.

A friend told me about this speakeasy and it was fun trying to find it without using a map. The bartender was very knowledgeable and told us the background of the drinks we ordered, all of which were delicious. You're not allowed to take pictures inside, and you must exit through the rear when leaving. It was a really fun experience that I would definitely do again when I return to Helsinki.

A hidden gem right in the center of Helsinki - perfect for a stylish drink before or after dinner. You have to find the hidden doorbell in a treasure chest before getting entrance - prohibition style :) A lovely dark atmosphere and very attentive waiters for the frame - but the star of the show are the drinks! Truly exceptional composition and flavors! A must visit.

Stepping into Trillby & Chadwick feels like slipping through a time portal into the 1920s. The entrance alone sets the mood—mysterious, secretive, and full of anticipation—like you’re about to join the ranks of shadowy detectives and smugglers. Once inside, the atmosphere is pitch-perfect: dim lights, vintage décor, and an attention to detail that makes every corner feel like part of a carefully kept story. The cocktails are nothing short of outstanding. Each drink is crafted with precision, presented beautifully, and infused with creativity that matches the speakeasy’s character. The music ties it all together, smooth and stylish, enhancing the sense that you’re part of a hidden world far removed from the streets outside. Special mention must go to Alexis behind the bar. Not only does he know his liquors with impressive depth, but he also carries the spirit of Trillby & Chadwick’s legendary detective history with charm and wit. Listening to him weave stories of the bar’s past while mixing a flawless cocktail is part of what makes the experience unforgettable. Altogether, Trillby & Chadwick is more than just a bar—it’s an immersive escape, where every sip and sound is wrapped in atmosphere. A must-visit in Helsinki for anyone who appreciates great cocktails, great storytelling, and a touch of mystery. Here’s the (delightfully pulpy) “history” of Trillby & Chadwick—note it’s a fictional backstory but still a very good one Origins (1898): The agency is said to have been founded in London by Hildebrand Trillby and Ashcroft Chadwick, quickly earning fame for cracking high-profile cases the Metropolitan Police’s Special Branch couldn’t (or wouldn’t) solve. Helsinki office & Prohibition (1924–1932): A Helsinki branch supposedly opened in 1924 to help enforce Finland’s prohibition laws. In a twist, that very office “went rogue” and became one of the city’s most profitable secret bars—hidden in plain sight and never raided. War-time end (1941): After Prohibition was repealed in 1932, the office faded from view and was destroyed by arson in 1941; the culprits were never found. Rediscovered files (late 20th c.): Decades later, building works allegedly uncovered a fire safe with agency journals and the founders’ diaries—material that “revived” the legend. Modern revival as a bar : The story now frames Trillby & Chadwick Detective Agency, a hidden cocktail bar in central Helsinki (run by Son of a Punch). The bar leans into the case-file lore across its menu and décor.

Secret speak easy themed cocktail bar. Very cosy. Nice choice of excellent cocktails.

From the moment you step inside, this speakeasy delivers a playful yet atmospheric experience. The dim lighting sets just the right tone—intimate without feeling gloomy—and the music adds to the mood, well-chosen -- and pleasantly unobtrusive. Service was outstanding throughout: attentive, relaxed, and we felt genuinely welcome, though we were walk-ins. The cocktails were a real highlight, both in presentation and taste—creative, balanced, and clearly crafted with care. On their 2025 summer menu there's a modified pina colada -style cocktail, and it's so tasty I had two. Lovely, small courtyard garden. While the prices are on the higher side, the overall quality and experience make it feel justified. A really well hidden gem with real character. We will definitely return.

We had a heck of a time finding this place! Look for the blacked out windows near a courtyard, open the door and head into their waiting area. We tried the phone at first, but it didn't work; thankfully we noticed a doorbell-like button and after pressing it were shown a table right away. We went on a weekday and it was pretty dead, only one other group inside, so if you want to check out this bar without the wait I highly recommend going midweek. The bar itself is intimate and mysterious, definitely has that speakeasy vibe, and we adored their playlist, it really helped set the atmosphere. The cocktail menu is fun, telling a story about each drink and leaning heavily into their detective theme. Drinks were great and each came with a fun amuse-bouche that helped enhance the flavor of the cocktail. There are no prices on the menu, but my cocktail was €15, which I felt was fair given the level of detail that goes into the drinks. The bartender was nice, answered all of our questions, and made excellent cocktails! We had a great time and I definitely recommend checking this place out to anyone in the city.

We could not find this place - walking up and down the empty street. We finally saw some people exit a courtyard and figured since they were the only people we saw for 30 min they must be coming from the bar. After wandering around the courtyard for a bit, we finally figured it out. Of course we find the back door of the place and were so middle aged American lame, they let us in the back door. The service and the drinks were excellent. I had a drink that came served in a milk carton! The drinks were excellent and the server gave us bar recommendations when he heard we were going to Tallinn next. His recommendations are excellent.

We were lucky enough to make the cut and be invited inside tonight. It's dark and mysterious as a former police interrogation building should be. Find the blacked out unmarked doors, then dial up the phone to get their attention and tell them the password. We waited about 10 minutes to get in, then our server explained the history, their three rules, and the drink menu. My husband started with the Eyes Full of Terror and I got Red White Lie - both were excellent. We weren't ready to leave after 1 so I got From Am to Pm and he got the bartender to make him a surprise. I loved my second drink even more than the first. It killed me not to take pictures of how pretty the drinks were but no pictures are allowed inside. All I can show you is the entrance. You should definitely check them out if you're in Helsinki!

Great spot. Unfortunately, the speakeasy is actually down the street from said incorrect tagged spot on google maps. So much history behind this space though, which makes it an interesting visit & find. Can't take photos though. They make you wait right outside the door 5-7min after they say they're going to be with you 'in just a moment' to keep their supposed appeal. That's annoying. The drink I had wasn't anything special but the components were somewhat interesting: makers mark, popcorn, Coca Cola, & lemon. Probably more but that's all I could remember. Tasty combo. I personally wouldn't go back because there are just so many other amazing cocktail spots with the same mysteriousness that have more creative concoctions, bartenders who actually converse with you, & no annoying wait times. I don't dislike this spot. But my expectations were not met whilst being here.

I've been to a few other speakeasies in the US, and this is right up there in terms of ambience. The menu is designed really nice as well, every cocktail has a nice backstory. Hipster as fuck. The drinks could honestly be better in my opinion though. Most of them seem to be on the sweet and lighter side, or served chilled. I would like to see more drinks that are darker or more bitter.

Cool speakeasy right in the center of town. Apparently owners have 5 or so speakeasies in central Helsinki. Curious since I doubt Finland ever had any inhibitions about alcohol (or anything else). I'm not craft cocktail kinda guy, in which these places specialize, but atmosphere is Prohibition retro exclusive metro-hip-ambient. Go for the experience.

I've had lots of drinks in my time, but hands down this place served me the best unique cocktail I have ever tasted. I'm not a gin fan so it was likely made with rum. It was labeled a ginger martini on the bill but it had a smokey and sweet twist to it. Chat with the server and/or the bartender and they can create you something perfect that you have likely never tried. There are 3 rules to this speakeasy: 1) No table hopping 2) No pictures 3) Exit out the back Find someone to give you the code to get in (if you can even find it). I was fortunate enough to walk by this earlier in the day and someone I was with pointed it out and gave me the password. The interior was cozy and 1920s feel - sitting areas with a library feel and dimly lit mood lighting. Nice background music and feel - I felt like I was back in time in an illegal speakeasy. It was a great experience.

One of the most outstanding places I've been. The atmosphere is amazing, the cocktails are unbelievable and the staff fit theme perfectly. It's the fight club of bars. When in Helsinki you must find this place

What a place! The speakeasy of Helsinki! Decor has really been thought out and it has incredible amount of details. Even the entrance has been made in a true speakeasy spirit. First of all you have to find the right door from katariinankatu and after entering you have to call with old school phone and the staff will come and either let you in or say how long it will approximately take. This place serves wide range of different drinks and cocktails and to my knowledge the cost varies from 11-13€. Also the staff will make special drinks to your liking if nothing from the list suits you! Definetely recommended!

Probably the best coctail place in Helsinki (and Finland). This is a secret bar near Kauppatori. Coctails are made of best ingredients available. Huge Gin Tonic list! Bartenders are great and atmosphere is awesome. If you like to drink good coctails - you must visit this bar!

Trillby & Chadwick is such an amazing speakeasy. You have to be a little detective to find the undisclosed black door from the short street and once you do, navigate your way in. However, once there you will truly appreciate their elegant decor, attention to detail and - most of all - the amazing cocktails they offer. Perfect for those secret afternoon cocktails or shady evening encounters it is also a great place for friends to gather up before or after dinner.

This bar took my group about 10 minutes to find and another 25 to enter. The bar was only 3/4 full when we arrived but they make you wait to maintain an air of exclusivity. We had some great cocktails and really liked the atmosphere, but I dropped one star due to the wait.

Must find the place first- blank entrance- black windows- have to knock on the large wood door and wait, patiently- then the small wood slider window opens so they can check you out ----the. Wait- limited seats - once you're in you're in. House rules- no phone- pictures- must exit out the back door - a real speak easy. The menu (book-hence the name and history of the place) is amazing! The drinks are perfectly fitting to the atmosphere and story of its creation. Absolutely SUPER

A true speakeasy! Finding the door is a challenge - it's completely unmarked. Look for a set of double doors with dark windows. Once you step inside, find the buzzer to summon someone. The interior is charming, the drinks are spectacular, and the staff is very helpful. If you're a big group, definitely book ahead. No photos allowed. :-)

Ring the phone. Ask for Mr Trillby. He'll let you know what you need. They can offer everything you'd expect from a modern detective agency. They'll find missing people or help you prove your innocence. But you won't be innocent by the time you leave this place. In fact, you may go missing.

Best cocktail ever- fin basil smash!!! Love the atmosphere and the story behind the establishment. The cocktail menu has the speakeasy's story and actual journal entries from the detectives throughout the menu! But...no pictures!

Excellent speakeasy cocktail bar with detective theme. Feels like entering another time and place. Cute toilets, good service and lovely atmosphere. I can warmly recommend for some tasty cocktails and nice vibes. :)

This place gets busy! But the cocktails are good and the staff know their craft. The first time i went was as a couple and we sat at the bar. The second time was in a group of 6 and we were told to reserve a table in advance. It contradicts the speakeasy nature of the bar!

A small and cosy cocktail bar serving very good drinks. It is a bit hard to find the place, but look for the black glass door, enter and call on the old-school phone.
