There are some special restaurants in Istanbul that can confuse you with their extreme amount of choices of food! Especially in Beyoglu, you can find such restaurants frequently. Most of them seem similar from the screen but each of them is specialized on something. Haci Baba is one specialized on meat! The prices are a little high comparing to the others but maybe because they have been serving since 1921 and they are famous.. I insist you to eat "Kuzu Tandir", you won't regret! Afiyet olsun!
