Papalina Fish Restaurant

Papalina Balık sits right on Ataköy Marina, serving up fresh seafood with waterfront views that are hard to beat in this part of Istanbul. The setting is relaxed and breezy, and the fish-focused menu is straightforward — you're here for quality seafood, not gimmicks. They also have a second spot in Bahçeşehir if you can't make it to the marina location.
