Buffet style restaurant. Had lunch there twice. Both times I could choose between two vegan menu options - different vegetable stews with either rice or bread. I got a small portion (650 HUF) and a big bowl of salad (530 HUF) to go with it and a chocolate-sour cherry cake for later (310 HUF). Though not very exciting or surprising in taste the food is good and very fresh (however, I did get there very early both times). I particularly liked the cake as it was not too sweet and sappy in a nice way.
There is free water and a 5% student discount with a valid (international) student ID. Additionally there is a small section with packaged goods for sale, mainly tea, Indian spices and snacks like power bars (vegan, gluten free, superfoods etc.).
The level of English among the staff varies but all of them were very friendly and asked colleagues and customers for help if they didn't understand or had trouble explaining something.
As the sitting area is rather dark and gloomy and tends to get packed fast during lunch time you might wanna consider taking your food with you to the nearby Danube.Pros: free water, student discount, good location
Cons: dark sitting area, gets very packed at lunch time
