This place is quite hard to review, but I'll try to be objective.
First the place itself: there's probably seating for about 75 people here, but we were the only ones. In the description it says it's a classy looking place. This is very far from the truth. It looks really dated, and the numerous decorations are shabby, kitsch and amateurish. It definately is a very personal style, but one which might be off-puting to some people. Others might find it hilariously weird and exciting (like me).
The food: I think there were not many vegan things, so we just ordered what the owner recommended. It was a LOT of food. All on one huge plate. Lots of potatoes, vegetables, tofu, pineapple and some couscous burgers. The burgers were very nice, the potatoes were good, the vegetables were very, very soft and the tofu and eggplant were a bit bland. It was boring, somewhat uninspired and amateurish. Though it was warm and filled me up good.
Service: the service was super friendly, fast and efficient. Top.
Overall: This place seems really to be stuck in the 70ies. Food culture has evolved a lot since, and people might find they can cook better at home. It's a bit hard to justify paying for this kind of food if you're not a tourist. Yet if you're very hungry or looking for a very unique experience you might want to visit here.Pros: Great service, Extremely weird decor
Cons: Boring food
