Yedigül Balik is a waterfront seafood restaurant located in Anadolu Kavagi, right in front of the ferry terminal.
It's a three-storey building with fish and chips shop at the ground floor and open and closed terraces on the upper floors.
Thanks to quite talkative personnel in front of the restaurant, you'll be in trouble if you'll pretend to miss this spot :)
After short hiking to Yoros castle we had about 1 hour for lunch and that was just enough to accept the offers to go inside and try one of Yedigül specialities.
We've chosen delicious grilled bluefish, but variety of fresh seafood is available, including fish soup, fish & chips, shrimps salad, steamed seafood, yellow tuna and other dishes.
Restaurant is tidy and clean with nice views over Bosphorus strait, personnel professional and nice.
Prices certainly lower than down there in Istanbul, e.g. on Galata bridge.
We can only recommend the visit. It is best to choose the fish you want to have prepared and to agree on whole fish price in advance, like we did.
It worked perfectly to mutual satisfaction :)
