The thing that they sell as arabic is basically heaven wrapped in tortilla bread. More specifically, it is texturized soy protein with some curry sauce together with onions, greens and tomatoes. You can also ask for some spices to make it a bit hot (but German hot, which means very mild). I had the same thing for two lunches in row and I could have probably had it every day.
You can ask for whole wheat bread as well for an extra 50 cents.
They also have burgers and baked tomatoes but I had the idea they mostly sell arabic and falafels.
