Found it by chance looking at restaurant reviews around Taksim. We were 3 and ordered the menu that the waiter suggested (30TL without drinks), which included a bit of everything. Mind you, we eat a lot normally but 3 menus is A LOT! A couple came after us and the waiter suggested 1 and a half menus for them, which is more than enough. I would suggest to do this, and order ayran to drink.
We stayed in the rooms upstairs which have pillows and low tables. The decoration is eclectic and worth looking at the details, the food was nice and the service fast. The atmosphere was quiet, so overall we had a magnific experience.
