Got there lunch today, was offered to take rice instead of bread, having started to eat saw its not just rice, turned out they use rizo, which basically a type of pasta which usually is made out of wheat. The guy at the counter assured me that rizo is a something you cook in wanted,, and therefore cannot have gluten in it. I didn't stay to argue and to get him to check it. Be cautious if eating there.
They have schwarma salad (schwarma meat on a green salad) which is really good and reasonably priced. Three stars because they don't have any specific accommodations for gluten free food prep, but they were helpful and should be able to feed you safely if they're not too busy.
