Although the restaurant is located in a hidden backyard you should make a reservation, since this place is packed with locals. In summer there are tables outside at the riverside, inside you can see the foods preparation in the big oven. The atmosphere is oriental and I have witnessed a turkish wedding here twice!
If you like turkish food you should have a try! Unfortunately this place is not cheap but all the ingredients are fresh and high-quality and they try to use regional and organic food. Bare in mind that there are some special dishes (Testi kebap) where preparation takes around 4 hours.
I've liked all the dishes I've tried here so far. The meat is delicious (Angus-cattle and Texel-lamb) but the vegetararian plates are also tasty!
