Was Kristóf Tóth at Burger 21 a mag?
Really enjoyed this experience! Good portions, clean restaurant, well cooked burgers and fries. Will definitely return.Only gripe was the small containers for self serve sauces. You need like 50 of those to get enough ketchup for an order of fries. View all feedback.

This is a decent burger spot. The burger itself wasn’t anything particularly unique, but if you're looking for a reliable place to get a solid burger—especially if you're not in the mood for a fast-food option—this place fits the bill. Just keep in mind that fries and sides are sold separately, which is why I can't give it 5 stars.

What a fantastic burger joint! The menu offers a variety of unique options that you won’t find at your typical burger place, and the sauce bar is a wonderful touch. The food was delicious, the staff was friendly, and the restaurant was impeccably clean. We also appreciated the handwashing station at the entrance for customers to use before and after their meals—something I wish every restaurant would have!

The best part about burger 21 is that they let all burgers modify with veggie patty. as vegetarian it is always hard to find a lot of burgers. but burger 21 does not disappoint them at all. they can any type of burger with black bean patty or impossible patty. I tried monterey, buffalo chicken replaced by black bean patty, bbq, and black bean . all were quite decent. they were best monterey and black bean if they don't know so much about BBQ sauce. it may be felt like that. but they are still not disappointing. a must stop for reasonable burgers?

Friends were as good as mcdonalds. the burgers are thiccc. I could fit it in my mouth to bite. great taste and the sauces are delicious. great variety for every taste they desire. our favorite sauces were the burger 21 sauce, ragin cajun and chipotle. the cheese sauce was okay, if you love American cheese, you'd like it. that was my first time there and the dame at the front was very friendly and helpful. in any case our new way to the burgerplatz!

Quite possibly one of the best burgers I've had at a burger spot. Their collection of different sauces at the counter are also very fun to mix and eat. Love the vibe! They also had an EV charger out front, so it was very convenient.
