ESTİ Karasu is a name on the nightlife side of Karasu — whether that's one option in town or one of dozens on a single street. Standing out in this category isn't really about who's loudest; it's about who keeps people around past that opening round — whatever it turns out to be. Place your first order, get a feel for the room, and give it twenty minutes — that's usually enough to know if tonight's the night you stay, or the night you move on.
