Gast offers a variety of foods--stir fries, pastas, pizzas, brunches--for 5 to 10 Euros. The food is good and the portions are well sized. The restaurant has a very modern feel to it: you walk through the restaurant to different "food stations" and when you buy something you add it to your account card, which you receive when entering the restaurant and give up when you leave (and pay). I had a Margherita pizza (6 Euros) and it was large enough for two people... I also had a salad with it to make it a meal for 2. I can also recommend brunch; for 3 Euros you get 3 eggs (scramble or sunny-side-up) and you can add breads and other foods a-la-carte.
