Went here after having visited the synagogue of Budapest, just few meters from Hummus Bar.
I was welcomed by a very nice waiter and felt immediately comfortable in there. The guest area is divided in 2 levels and nicely decorated, with cool quotes written on the wall.
I sat down, another nice waitress came, brought me the menue and a free mint tea. I ordered a home-made lemonade and the Falafel main dish. This includes Falafel, 2 fresh and warm Pita bread and then one can chose 2 side dishes from Hummus, salad, rice or...some other option. I took Hummus and salad. I was in Falafel-Hummus-heaven and superfull afterwards. Nonetheless I ordered a Baklava as dessert - also very nice and came with coconut flakes on top (never had it like this before, but was really tasty).
I can only recommend going there :)
