Karakoy Fish Wrap is a seafood restaurant in Istanbul that serves mackerel kebab, fish wraps, and mussel rice. It uses half a thick mackerel, removes the bones, and fills it with vegetables and pomegranate seeds. Chai tea comes free and mussel rice is sometimes served as a complimentary side, so it can be eaten like a local snack. Card payment takes a long time and the machine does not always arrive right away.
