This is one of my favorite places in Istanbul.
The service is simply at the highest level, you can have a pleasant conversation with the waiter, he will tell you in detail about the dishes, help you customize them to your taste preferences.
The service in this cafe did not wait. At first they put us in jail, they waited for about 10 minutes. Then I went to look for a waiter, because everyone else didn't give a shit. As a result, we were given a piece of wood with a QR code on the menu. The price tag is not cheap, to put it mildly, but that's not the point. After that, the staff also disappeared after waiting for about 20 minutes they left.
