The best.
The service is fast and the portions are huge - the complimentary bread and oil is the best I've ever had.
I recommend the ispanakli borek (spinach feta fillo) and the potato dumplings with curry and yogurt. Get the yellow split pea soup if its available. My meatier friends have told me that the tavuk dolmasi (stuffed chicken breast) and the kabuk dolmasi (acorn squash filled with chicken and tomato sauce) are wonderful as well. The baklava is made fresh by Husnu himself (who you should try to meet while there) and it is so very good. Also, I've never had better rice pudding in my life.
