Mario's Osteria

Easily one of the top 3 burger places in Bucharest. Their smashburgers are flawless and you have an option for everyone : italian for the fresh style fans, Korean for the spectacula spicy Gochujang sauce or even a Classic for that old scool Mickey D’s taste.

Also they have a mini / slider version of every burger so you can try out more than one or have a good option for kids.

Sharing the same food hall with Ironic taproom - a craft beer goodieness - is another plus

The staff is nice with straightforward menu.
I took the mugian burger, came as they said after 15 minutes, very juicy and flavoured! Wish it was a little bit bigger 😅 On the side fries with parmesan that were so fresh and sweet by itself feels homemade quality

Probably in my top 5 “Best Burgers” I’ve ever had. We tried the Classic Burger (41 lei), the Truffle Burger (49 lei) and the parmigiano fries (17 lei) with garlic mayo sauce. Absolutely crazy delicious. We will be back 100%. The size of the burger it’s perfect, the meat is smashed and perfectly cooked, the buns are to die for. 🍔

The burgers are simply so good! They are juicy and very tasty. The fries are very tasty too, the oregano ones were our favourite.

My only problem was that they didn’t have ketchup…. Who doesn’t love fries with ketchup?
Still, they deserve a 5/5. Highly recommended.

Wow. Burgers are great. Not super big so fries may be needed if you are hungry but very tasty!!! Great selection of crafted beer! Very nice staff! Fully recommend!

WOW! That was one of the best burgers I’ve ever had. And to mention that I wasn’t hungry at all. Great quality, the meat was perfectly cooked, well done but soucy, the bun was delicious 🤤, the fries were in a big portion and super tasty, anyway, overall such an awesome place for a burger 🍔

Best burger I’ve had in a very long time, better than most “famous burger restaurants” the fries are also homemade and very good. I recommend the truffle burger and oregano fries. Only downside is if you wanna eat there; there are no soft drinks available, only beers and some lemonade which is not very good.

Really great burgers! Tasty and juicy, with a good amount of sauce. Fries are good. Loud place, lots of choice for beers on tap.

Very happy with the mini burgers as you get the chance to try more. Nice and what you would expect for burgers and fries. I loved the beer options and I was excited by some discoveries.
The orders are made exclusively at the counter, no table service. No cash payment accepted, only cards.

Overall a qualitative food, the burgers are good, the fries, on the other hand, are the best, made from freshly cut potatoes, with parmesan (or grana padano) cheese and herbs.

Stumbled upon this great burger joint by coincidence today.
I ordered the Romanesco burger. What a great hamburger! Super fresh and good quality ingredients. Burger was made by order.
The quality of the beef is awesome. The bun is great. The horseradish sauce is well in balance (not too sharp).

I can't understand that I was the only one (around lunchtime on a Thursday). Anyways: I think I'll lunch here again tomorrow and try another burger.

Lovely burgers in Bucharest. They serve a wide range of lagers, pale ales, IPAs, cider as well.

A quiet place, just opened up, very welcoming. Their menu is small but boy is it well executed. I got the truffle burger and my wife got the korean. Lovely taste. And their fries are divine, in-house made. Craft beer available too. Stop by, you won't regret it. We spent 110 RON for those two burgers and fries.

Really cool authentic place with tasty fresh burgers. 🍔

There are rumors that here you'll taste the best burgers in Bucharest.
I have not tried all places where you can get burgers, but from the ones I visited, indeed these are the most delicious ones.
The legend goes on!
Must try, then go get a coffee from @Velocita.
The music at this van is great too.

A delightful surprise, in the middle of expensive and crowded Amzei. Juicy meat, very tasty, wow bread. And fresh potatoes, absolutely delicious. I recommend a visit here, it is not crowded, it makes your taste buds explode and it is inexpensive.

Very, very nice burger! Decent potatoes also
Unfortunately i was too hungry and didn't take a photo of my burger. I got the one with the black truffle and was super delicious.
Totally recommended if you're looking for a nice street food!

Great burgers, the freshest you can get. Big sized potatoes portions. Awesome unfiltered beers.

I got the black truffle burger and the parmesan fries and everything was really delicious. Unfortunately, I was the only client dining there at lunch time :( hopefully this place gets the recognition it deserves very soon.

Still one of the best burgers I’ve ever had, it’s a new tradition to come here ever time I visit Romania.
Service was amazing by Bianca as well 👌🏼
