Namli Kebap is one good kebap restaurnats (in 1. Levent).
Lahmacun is an interesting item. Don't order much than 2 pieces of lahmacun. Eggplant kebap is a good choice. If you go Namli Kebap, iskender (doner with yogurt) is very popular. Shish kebap and all other sorts of kebaps are serving there. People go there for the best kebap. For dessert, I suggest kunefe, a dessert with cheese. It is served hot and it is very tasty.
