when i visited istanbul last week (november 2018) i was very excited to have dinner at chelai, i was informed that no reservations will be taken on weekends, so me and my friend called a taxi and went all the way to have dinner on a saturday night, it was 8:30 pm when we reached the restaurant, the guard at the door was so rude and didnt let us in, i told him we are here to have dinner, he didnt listen and said out , no entry two guys! this turns to a club. this was the most humiliating non hospitalized thing i ever experienced. with all the recommendations i got from my frds who tried this restaurant, if i visit istanbul again i will try it and will think of changing my rating based on their hospitality.
