If you are trying to have fast food in Istanbul, at least make it turkish. The restaurant my friend too me is basically the McDonalds in turkish version. (but I am quiet sure you can't find burgers here) So everything served here are basically turkish foods: grilled meat, bean soup,turkish sweet (baklava with Pistachio)... The one I had on my photo is a kind of Turkish pizza called "Pide Cesitleri", it's kinda like pita topped with pepperonis. Very thin and crispy.(I do hope it to be a little bit more cheesy) I recommend you to give it a go, you will find how different it is from the fast food chain you think!
