Illegal Burger

I came here expecting a good burger… but left with way more than what I asked for! This might actually be one of the best burgers I’ve eaten in my life. And I’ve eaten thousands, no kidding! My order was: Gourmet Deluxe (double patty) and potato wedges (that they called grilled potato). The smokey but still very juicy patties worked like magic with the richness of the Brie and Gorgonzola, the oily crunch of caramelised onions, and the piquant truffle mayonnaise! Every bite was a delight. Even the wedges, as simple as they looked, were so crunchy on the outside and creamy on the inside, with a generous sprinkle of salt shavings. A true knock-out burger! Last but not least, the wonderful service! You don’t really expect someone to make your order fresh a la minute and serve you at your table… but they do it, with a big smile! To the very friendly man at the counter today, you made my day (and probably many others’ too).

Meal was pretty amazing, the potato wedges had a delightful sprinkling of shaved salt that went very well with the truffle mayo. Burger itself was also amazing. Wish I could it at this place once a week if not more.

I guess this could be the best burger place in Oslo. The smokey meat is awesome, everything is well ballanced. I’ve had a lot of burgers in my life and this was quite impressive.

Best burger in Oslo hands down! Simple flavors done well, great fries too. Highly suggest

Burger was GREAT! They have only HARD POINT seating. So if you're bigger than normal A4 then you got to stand in the window showing everyone you're not A4. Since i love the burger so much i would advice buy and go! PS. I did pay tips(20%) but my friend didn't. And ordered my burger at the same time than my friend but got it at the same time. So tipping wouldn't give you better service or quality of burger.

I had the Gourmet burger and it was amazing! The bread is nothing to rave about, but the contents, 10 out of 10. The potato wedges were also amazing, fluffy on the instead and crispy on the outside!

Good burger but...it could be better. Good service but...missing the vibe/atmosphere as it's a bit cold inside. The name of the place is catchy but...i think it doesn't match the menu. Illegal Burger is nice idea BTW🤩.

Excellent gluten free burgers. The guys are so careful to make sure the food was gluten free. The potatoes are amazing too. Also they have an amazing garlic mayonnaise.. I ate there for three nights straights..

We went over to Illegal Burger after landing in Oslo, and we were dying for a good meal! Our hotel was just down the street from Illegal Burger and so we decided to go give it a shot! I think everyone should make a quick stop if they are in the area! I got the Illegal Spessial - a chorizo and cheddar topped burger! This was so wonderful, with guac and other special sauces lathered upon it. I really loved this burger, and it was paired wonderfully with tiny fried potatoes! Super delicious and worthwhile!

Service was good, food was ok. A GF bun is available (which is always appreciated). Definitely city prices for a kind of dirty/funky place. Our party only had burgers. All walked away a bit hungry thinking we should have ordered fries.

You won't be disappointed if you're looking for a quality classic burger with plenty of options to dress it up or down. The store front doesn't look fancy and you order at the counter but the quality of the burger makes up for the ambiance. Fried potatoes with dipping sauces are a nice add, as well, and one order is enough for two people.

Small place. Took a little while to get the food. Fries came first for some reason. Burger was pretty good.

Illegal Burger has done some good PR. After having it pop up on my radar several times, via different style blogs, I bookmarked it for my next trip to Oslo. When that trip came I found it located a few steps from my hotel (lucky me)! They do an excellent drippy, juicy burger that's packed with flavor and not overcooked. The accompanying potato wedges are nice but may not satiate if you've been craving fries. Aioli lovers will be pleased with their offering. Skip the beer unless it's a label you recognise. Trying to be adventurous, I tried the Herslev Økologisk Hvedeøl and found it uncomfortably bubbly. I dined here with a serious beer drinker and it took him the entire length of the meal to uncomfortably stomach one bottle. But beyond the beer, Illegal Burger's a good bet.

Good burger nice French fries and tasty as well . Definitely recommend not super expensive

I went to go visit my brother in Oslo while he was studying abroad and we were looking for places to eat. I will admit that a burger in Norway isn't my first choice since I love to be adventurous, but food in Oslo is pretty expensive compared to what I'm used to! He raved about this place and said he takes all his friends there when they visit, so we decided to just try it out anyway. My first impression was that I loved the design. The interior, logo, menu, etc. we're cute and fun, and being a graphic designer, I appreciate that stuff. I don't regret it because Illegal Burger was SO GOOD. The burger was delicious and the fries are a must have! They were wedges and one of the best I've had! The dipping sauce was amaaaazing too. I would definitely go here if you're in Oslo! So good!

Simply the juiciest, sloppiest and tastiest burgers this side of the Atlantic. Fortunately two outlets in Oslo, both equally munching great!

Excellent burgers, and the fries, the best. Pretty crowded and you must wait to grab a table, totally worth it. Excelentes hamburguesas, y las papas fritas, las mejores. Mucha gente y hay bastante espera para sentarse, vale la pena.

burger patty was on point,but i dont think its the best burger in town,the laid back set up was like a food chain (not bad) we got seat tight away,service was good as well

I am glad I visited illegal burger! Had heard a lot about it and it was indeed worth a visit! First of all it is fast food. So don't have expectations of a fancy type of burger. However it is a fancy fast food place, if you can say so! For example: the burgers come out in paper wrap but however on a real plate. This is the kind of balance this place has which I love as a concept!! The food was great! I had number 7 and it was not too spicy. The fries come with aioli which I love and are delicious as well. The meat is left juicy and the burger is quite balanced as a taste. The food was enough for me, although in the beginning it didn't seem like much. The beer comes from Mikeller in Denmark! Felt like home and i can't brag about mikeller in an Oslo food place's page but it was indeed really good and worth trying!! The interior and concept I loved!! You order on the counter and you wait in a line to get seated. So many people on a Tuesday evening! But luckily as it is a fast food restaurant it is not really a place to spend all your evening at. It's more like eat and leave concept. Which seemed to work quite well as the line never got bigger than 2 tables. So remember the idea is to have a good burger and not a cosy night. If you keep that in mind I am sure you will be satisfied with this choice. Extra points for service too! Generally: I am happy customer!

Honestly, this was a pretty disappointing experience after reading all of these amazing reviews. I suppose that relative to other burger places in Oslo, perhaps illegal burger is an exotic and interesting option. However, as far a burger quality is concerned, I would not say that illegal burger is necessarily great. More like mediocre. I ordered the Illegal Special, which had avocado and chorizo in addition to tomatoes and lettuce. I suspect that the folks in Oslo weren't actually referencing the whole immigration situation in the Southwest US when they named the place (given the 5000 mile difference) but it could be interpreted that way for better or worse. Regardless, the chorizo was chewy and there were not nearly enough avocados or salsa-like flavor to evoke a Latin America type of experience with the burger. The potets were fine but not special in any way.

Decent burger, but nothing special. I stopped by with a few friends, and I split the hot mama deluxe and the illegal special with a friend. It was fairly tasty, but I thought the meat wasn't that juicy or flavorful. I didn't find the toppings to be that value-adding either; I didn't think the guacamole added enough different texture or flavor, while the chorizo in the Illegal Special gave it a bit of an interesting kick, but probably something I could have done without. It's not a bad meal, but I wouldn't go out of my way to come eat a burger here.

I ate the HotMamaDeluxe with extra Cheddar, Wedges with Sea-Salt and a Ginger beer. the Burger: Meat was ok, not the bomb but ok. I prefer a lot more spice with the ground beef but it may be some cultural thing to not overly spice up the food here. Anyways... they grill it over coals and when you come into the store you can enjoy the nice bbq-smell. too much guacamole for my taste and somehow I was missing some hot sauce too it but thats just my taste. BBQ Sauce was a little too mild and didn't come out too much I didn't like the 'cut the salad in little strips like Mcdo. does... it falls off the burger easier. but salad is salad, jus sayin! Cheese was good, had cheddar on it. Great cheese!!! Wedges were good, I like the sea-salt too! All in all: Burger is OK but it doesn't really give you that WOW-experience. It lacked a little spice. Too neutral for my taste. But go paint ur own picture! Great Vibe, warm and welcoming although the store is small they had good music (hip-hop, rnb and soul... I had the impression they were completely playing all my fav music) When you are there you have to try the ginger beer. I tried it for the first time and I really like it. Try it! I payed 242Kr=28€(that time) for all that, way to expensive for my german wallet but yea.... that again is Oslo. #RapeYourWalletPrices on EVERTHING you see!

Inconspicuous from the street and (if I am completely honest), pretty soul-less looking from the inside with an easy wipe clean floor and linoleum tables that remind my of a by-gone time at McDonalds. Don't let this fool you into thinking you are about to get a plastic bun with an even more plasticy burger, this place serves one of the best burgers I have ever eaten! It is a sizeable and hearty meal on its own, add to the mix a side of chips and aioli and you have a recipe for a full stomach and an elated palate. NB, an important point for those of you that love a beer with your burger: they serve 2 different beers there, a local and a basic one (Carlsberg I think)...if you are tempted to go local (as I was), be ready for the fizziest experience of your life. I like my beer, I pride myself on having a quick decent when it comes to having a beer with a meal...I could not finish this beer, it caused me so much gas it was painful and it took over 40 minutes to get to where I left it, even though i was actually trying really hard to finish it. Nice taste, just wish they (the brewer, not Illegal Burger) could tone down the bubbles a bit. Beer issues aside, you are guaranteed a fantastic burger in a pretty nondescript room that sits above a rather noisy nightclub....I like it, I like it a lot :)

Yep, it rocked. Just like everyone said it would. My true love & I had the Hot Mamma Deluxe and the Blue Cheese burgers. Of course we also had the potato wedges & aioli sauce as well. All totally delicious. If I went back, I would ask for a few more jalapeños on my burger, but I like it extra zippy. With regards to the beer, some other illustrious Yelpers did not enjoy the local brew. We each had a pint of the light Frydenlund, and it was a perfect accompaniment to the burgers. We did not find it unpleasant at all. Everything was super yum!

Lived up to the hype! Got the Illegal Special & got one patty which was more than enough. I believe the secret is the way they grill & season the meat-charcoal fire giving it a perfect smoked taste. My burger was cooked a perfect medium as promised. Now the place is smaller & it is a fast food joint & not sure if this is the best burger in Oslo but has to be one of the best!

Best burgers in Oslo. Nice atmosphere and decent beer. Good service and prices are okay

Illegal Burger -was- the undisputed best burger in Oslo for a period of time, before a major uprising of new burger joints in town make Game of Thrones look tame in comparison. I wouldn't call Illegal the best anymore, but it's still in the upper class. The first thing you notice is the overpowering smoke - not in a good way. The meat is smokey, the bread is smoked, the lettuce is smokey, and after your visit you'll feel like a beef jerky. I thought I love smoke, but this place pushed me to my limits. The meat is actually fantastic, but the smokiness did a disservice to them. The sauce might have been good? I ordered a double cheeseburger and this might be a paradox - there was too much meat (???) in comparison to the other toppings and sauces. I didn't think they balanced the proportions well, so tip: stick with single meat next time. On top of all that, the smokiness shrouds the rest of the flavors. The burger felt all meat-and-smoke, a little lacking of other personalities. Given all this, I still enjoyed my burger. Guess I'm a meat-and-smoke guy after all. One last thing: the potato wedges are really nice.

Best burger I've ever had. As an American I've eaten a lot of burgers so this is really saying something. Have the Hot Mama Deluxe and thank me later, don't forget to order fries! Their homemade aioli is delectable.

I still find this the best burger joint in town. Great selection, service and food in a small funky place.

Sorry guys, I wasn't a fan of your hamburger meat! The burger I got was not my personal favorite, but if I come back to Norway, I will probably get chicken or the turkey burger instead :) I will compliment you on how AMAZING your french fries are, I could eat those babies every day! I still recommend coming in because my friend swears this is her favorite burger in all the world, it just wasn't mine! I'm very picky on my meat, I'm weird. They have beer and wine (I believe) and it's a small little joint, so beat the rush and come early. My friend said they'll have a line out the door at times!

We went there on a Saturday, we had to wait 10-15 min for the table and the burgers, but it was worth it. The same quality as always + great service :) The "illegal" special was very good. You can select your type of meat or vegetarian one for each burger they serve. On the minus side, since they cook the burgers right there, it can get smoky in the room.

Amazing! Great buns that remind of French toast, nice grilled burgers and the burger dressings are great. One of the best burgers I've had.

There's an amazing burger called The Vegan here (Double). Best burger I ever tasted! It was so good I had to try the fries. It was equally satisfying. I was also shocked by how fast it was made. I don't know what planet this cook is from but he's not human.

This is the second time I eat here and I have made up my mind. The first time I ate a bluecheesebacon hamburger, yes that is the name all in one word, and it was good. I'm not the biggest fan of blue cheese because many can't introduce it properly in to the food. Illegal Burger did manage it fairly well I have to say, but the problem I had with that burger was that it was more salad then anything ells. I have heard rumors about this place a long time and frankly it didn't bring the WOW!-factor that I was expecting. I then decided to give this place a new chance and this time I stayed in the restaurant and ordered a complete meal. This time I ordered a Cheese Royale and some deepfried potatoe boats. To wash it all down a plain and simple coke. I got a seat fairly quickly and the food not long after. This time, knowing what to expect, I could make a proper judgment. The burgers are okey, not great. I was expecting a bit more cheese or at least a bit more cheese taste of a burger named Cheese Royale, but it was almost like a plain normal burger. Potatoes was cold (only a few of the ones at the top) and the thing that made them great was the Aioli. Really good in fact and I recommend it if you are gonna sitt there and eat. If you are unlucky the line to order can be long and the line to get a seat will be even longer. The second time I was there at a good time, not that many people but it still felt a bit crowded in there. The bar/order area is quite nice and friendly and the atmosphere can be pleasant if you don't mind it being a bit crowded at times. The waitresses was friendly and welcoming. All in all it is an okey place to grab a burger but it falls a bit short to be the best burger. Don't expect an foodgasm.

After all the hype about Illegal burger on Yelp, I was so excited to check it out. I smiled through the 30 minute wait and sitting on the cramped uncomfortable stools. After all, its not everyday that you get a 90 nok burger in Oslo which is also supposed to be "the best in the city". I love burgers and after a long time and research had already found the best burger in Oslo (which is even better than my fave in London). But i wanted to check this out. My husband ordered the truffle burger and I ordered the Hot mama with the potato aioli. Can I just say - BOTH the burgers were horrible, tasteless and horribly made. Hot Mama was far from hot, in fact the salad inside made it cold and bland and tasteless. I had to soak it in ketchup to wash it down. HORRIBLE!!! the Truffle burger was slightly less bad than the other but horrible nonetheless. The potato wedges were pathetic, soggy and old. And the aioli was equally bad. Even my Pepsi Max was warm. Please please please, if you want the best burger in Oslo, head to Døgnvill Burger which is hands down the best burger with a great ambience. and its not even far from this rat hole called Illegal burger. http://dognvillburger.no/oslo/ the price is 50 nok higher. And for those of you who want to get a great burger within this price range, please get a whopper from burger king. A hundred times better. I kid you not. Oslo doesnt really have the best food but its not this bad. Dont settle for this lousy place and ruin your lunch/dinner.

I come from the land of a fancy burger: San Francisco. Heck, I even make a great fancy burger at home myself. I even occasionally make my own buns when I feel up to it. The mister and I had been traveling for about a month and it was time for a good burger, so I was excited to see there was supposed to be a great place in Oslo. We came on a Monday late afternoon and it was pretty crowded even then--usually a sign of a good place. We tried the Hot Mamma and the Illegal Special. We had to wait a bit to get our food, so this is also usually a good sign for a burger place. It usually means they're making it fresh. When the food came it looked great, but when you bite into it, it's a hard puck of meat with condiments that don't do anything for the overall product. I doubt the burger patty had a panade because it was so dense. It was also overcooked with no pink in the middle whatsoever. I know it can be a cultural thing not to eat meat unless it's fully cooked through, but for my taste, this was less than desirable. The two burgers were not very distinguishable from one another, which was also depressing. We like variety when we eat and somehow, these ended up being almost the same. Also, just to note, the Illegal Special has chorizo on it, but it was unlike any chorizo I've seen before. It was thinly sliced instead of a spicy sausage that I'm accustom to at home. I don't dislike this place because of this differing expectation, but I dislike this place because it was bad. The service was nice, but the food was truly disappointing :(

Scene: walk in. "OMG, so many people" The place was standing room only. Then my party and I were told that we have to order and then wait 25 minutes for our food. "Wow", I exclaimed! There is a reason for this. The burgers! This place is supposed to have the best burgers in Oslo. And they are right! Burgers only get better at Pilot Butte Burger, but that is another review in another country. I ordered the GreenChiliSalsa burger (#7 on the menu) with jalapenos, which are not standard on the burger. When the burger finally arrived I must say that I thought I was at McDonalds. It was a patty and cheese between two buns. Pretty pathetic looking! A slight mix-up in the order made them think I didn't want anything on it, so it was quickly fixed and I received back a burger which was almost spicy and very flavourful. It was washed down with a glass of Frydenlund Bayer. The volumn of the music they played could have been a bit lower. It was difficult to hear the person sitting across from you without having to yell. If I want loud music I will go to a bar, not a burger cafe. I will be going back here. Next time I will bring my kids and see what they think of the food.

Gahhhh I love this place! Gluten free buns and fabulous quality meat. If only they had sweet potato fries..... Anyways we came here just as it was getting crowded. So we had to wait awhile for seating, but after you order your food you just hang around scouting out people who are finishing so you can grab a table. I wouldn't recommend coming with a large group....Once the food came I was so stoked to be eating a full burger with bun and all so I really can't complain about anything. I loved the flavors and couldn't believe how long it had taken me to go there! The only thing I wasn't to keen on was the "potato boats" I'd rather have actual fries or sweet potatoe fries. Other than that I am a fan and will be back :)

Just a Burger? Just a burger. Robin, it's so much more than "just a burger." I mean... that first bite-oh, what heaven that first bite is. The bun, like a sesame freckled breast of an angel, resting gently on the ketchup and mustard below, flavors mingling in a seductive pas de deux. And then... a pickle! The most playful little pickle! Then a slice of tomato, a leaf of lettuce and a... a patty of ground beef so exquisite, swirling in your mouth, breaking apart, and combining again in a fugue of sweets and savor so delightful. This is no mere sandwich of grilled meat and toasted bread, Robin. This is God, speaking to us in food.

Believe the hype! Pros: *Manually cooked (read: no grilling machine involved) burger patties that retain juiciness, creative and well balanced flavour combinations *Burgers that do not suffer from "height syndrome" (my boyfriend's name for burgers piled too high for eating without a knife and fork) *Excellent potato wedges to go with your burger Cons: *The space is too small for accommodating all the hipsters and burger lovers in Oslo that would like to eat *The seating furniture is a bit in the uncomfortable side *Service takes a while (which means good burgers, but which does not help with diminishing the queue) Go outside the hours where you would expect the masses to crave burgers (read: early or very late friday or saturday or sunday afternoon are bad choices). Oh, and don't order the veggie burger - it is a sad, dry soy-based substitute for a meat patty, and this really isn't a place for vegetarians, sorry.

I'd like to put a caveat on this review to say that I have had lots of burgers all over the world and while Illegal Burger is the best burger I've had in Oslo, it's not up there with the 5 Napkin Burger, you know what I'm saying'? The burgers themselves are really good. They're juicy, lots of meat, great sauce and you need two hands to hold it. The blue cheese is my favorite. The wedges are ok, the aioli is better. They have a few beers and hipster soft drinks to go with your burger. If you're from a culinary capital like New York or Melbourne and you hear about this "amazing burger joint in Oslo," just take stock and remember that you're not in a country full of Angus stud farms. If you consider that then you'll be mighty impressed with Illegal. Get there early. There is hardly any seating and this place gets PACKED!

So it's said that Illegal Burger is the best in Oslo. Now, I don't know if this is true because I haven't yet been to all the burger places in Oslo) but it sure is delicious! The patty is definitely one of the best I've had, and a single is filling enough on its own, but if you're tempted by getting a double, go for it! Just make sure you haven't eaten all day, because your burger is going to be HUGE! :) The potato wedges are a bit too greasy for my liking but the aioli it comes with is divine, which totally transforms the experience. It's frequently crowded, so it's easier to get a table if you are in a smaller group, but the wait is definitely worth it.

Spent many delicious afternoons here. Friendly staff, amazing food. I keep bringing my tourist friends here, and they love it too!

Good big burgers with plenty of flavor. Potato fries were great with coarse sea salt & dressing on the side

Great burger and beers. Usually you have to wait a while to get seating since there isn't that many places to eat. Would be nice with more seating is my only complaint

What's the best way to start your city trip? By having a great fat burger! We landed late in Oslo and were starving but our options at this time were very limited. Lucky me, my sister lives there and knew how to make us happy. Even at 10PM this place was crowded, either people eating there or taking away. It looks a bit like a fast food but you can easily sit and take your time. I went for the classic cheeseburger and ate it so fast that I was sad it was already over! It tasted delicious. It does deserve its reputation of best burger in town. French fries are more fried potatoes, great too! Prices are reasonable for the quality (and the city). Top choice!

Beef tastes a bit off and the wait is too long even when they are not busy. If this is the beat burger in Oslo maybe don't eat burgers. Fries are not included!

The best burger I've eaten in Oslo. Not much of a compliment really. I've rarely eaten a good burger in Norway. The food comes pretty slowly but tastes damm good when you finally get it. I always get the Hot Mamma with bbq sauce and guac.

Nice clean burger shop at the heart of the city. The place is rather minimalist but at least clean (always an issue here). Nothing really exciting but cheap classic burgers.

Trying to eat through the menu and it is quiet nice! Being a small place you might have to wait a bit but the burgers and the fries are worth the wait. The gourmet burger is nice and the hot mama deluxe is great.

Awesome burgers for a decent price! Fresh buns, meat, and toppings. I liked the mushroom burger. Go at a random time to avoid any waits for a burger!

So I read Yelp and decided to try something illegal! The reception upon arrival was confusing as loads of people there standing, I thought waiting before I say others go up to the counter! The service was ok, 30mins wait, but the blue cheese burger was good! The illegal beer to wash it down was perfect! Thanks for a great burger experience!

Really enjoyed this atypical burger joint! It can get quite crowded and the seat number is quite limited. Nonetheless they do serve some of the best burgers including vegetarian in town! Enjoy

Do I dare say I really didn't care for this place? It is small. It is impossible to get a place to sit. The tables that do open up are never cleared. The food itself seemed fresh enough, but back off on the fake grill taste and do you really need to add it to the fries? All I could taste was that grill taste. It was overwhelming and I was done with it less than half way into my burger. My husband on the other hand loves it and was more than happy to finish my meal. He can't stop talking about how good it is so if you like a smoky grill taste, you will probably really like it here. For those of us who like to taste the cheese, meat, and all the extras on the burger and not just some added fake taste, you should probably stay away.

Great concept. Friendly staff and funky seating area, but the "best burgers in town" should be bigger and juicier without having to go double. Johnny Rockets is my reference point for a classic burger, but they aren't in Oslo ... Yet!

This place had decent food (3 stars), but I'm giving one star because the service was AWEFUL! We ordered our burgers, and we were told it'd be 30 minutes. We came back and were told that they had given our burgers to someone else...but to come back in 20 minutes for new burgers. We came back and they hadn't even started making them! We had to stand there watching them to ensure our burgers were made. It took 1 hour and 15 minutes until we were eating our food. A TERRIBLE experience.

I´m a fan:) This place has pretty good burgers, only thing is when I pass to work it is usually closed. Not open for lunch, but open late. Have not been lately but usually has DJs and pretty good service.
