This restaurant is located right in the heart of the Vienna University. This makes complete sense once you realize most of its customers are students, who like to eat good for cheap.
This is not going to be perfect for your wedding anniversary. It's set up as an all you can eat buffet. You go in and hopefully can find a "diner style" table. It has two seating areas, upstairs where the food is located and downstairs (by the kitchen?)
It's very bare bones, utilitarian. That being said, it's all you can eat buffet and the best part is that you pay what you want. So you could eat several plates and pay 5 Euros, for example. Half of the buffet options are always vegetarian, great for my vegetarian wife. We've eaten there several times now, always leave feeling full and enjoy a glass of wine or a pint of beer with our meals. The drinks' prices are written on the menu (no pay as you go for drinks).
The food is hearty, filling, and good.
All in all, we enjoyed the food, the drinks, and the concept of all you can eat "pay as you go"
The staff is friendly and they speak English (at least one waitress did!)
If you're looking for some decent, filling (Vegetarian) food on the cheap, this place comes highly recommended.
