Karadeniz Doner is a shop near the Besiktas harbor in Istanbul that serves lamb doner as a sandwich, durum, pide, or with rice. The meat-focused composition comes with two slices of tomato and one pepper, and you can choose thick bread or a wrap. Seating is on the second and third floors, with a restroom on the third floor, and even when the line is long, the turnover is fast so your turn comes quickly. The shop is very small.
