What's Beef — Restaurant in Dusseldorf

I decided to go here since all the Japanese restaurants nearby were too busy. The entire restaurant is extremely confusing. I ordered my food and drinks like it was a fast food place and then sat down at a random table. I didn't get my drinks, apparently, you have to get those yourself. The tables didn't have cutlery, you also have to get these. But then the food was brought to me by a waitress. The staff did not ask if I had been there before or knew how it worked so I was very confused the entire time. The staff also did not make me feel welcome. I felt like I was being stared at and judged. When the food came, it looked pretty good but it just tasted off, maybe it was overcooked im not sure. I liked how it was served on metal trays and pans, very rustic. The decorations are also very well done. It just needs better service. I saw one of the staff members asking a large group of customers to move for another group, this in my opinion, is very unprofessional. So to wrap up this review, bad service, okay...

The food was nice and the menu included vegetarian and vegan burgers. The entire menu was in English which made it easy to understand as a foreigner and the location is quite close to the station which was convenient. The prices were very reasonable for a burger place. The atmosphere & decor consisted of pop-art style portraits of famous people all over the wall with only hip-hop music playing in the background, which gave it a kind of young, African-American vibe.

Went with my dad and we both had the No'Muh Burger which was delicious albeit a little difficult to eat as it kept slipping out of the bun. The sweet potato fries were nice but the Yuca fries were a bit bland (although I put that down to the Maniok root rather than the chef). The BBQ sauce had a good flavour. The milkshake was extravagant, although the cheesecake in the drink was a bit bland and I regret not having gone for a different one instead, but otherwise...

Went in to grab a burger because the rest of the restaurants were all closed. My girlfriend and i both had one burger with cheesy fries. Having a severe dislike for ketchup and mayonnaise I asked if I could get my burger without sauce, they said yes and wrote it on their order to see(see picture). After getting the order I always check if there is any sauce on there or not. As you can see in the picture there was more than enough still on the bottom and top of the burger which I proceeded to annoyingly scrape off. I would assume asking this doesnt happen a lot and the "cooks" just go auto pilot on the prepared open buns spraying sauce on there mindlessly.(This i saw them do when i was ordering.) Also be prepared to wait approx. 45 min to get your burger. If I were allergic this could have been fatal. To bad this ruined my mood and experience, the fries were ok, the burger for my...
