Under the Galata bridge you find a handful of colourful boats that sell amazing fish sandwiches – balik ekmek. Basically, fresh mackerel is grilled on these boats, then stuffed with a bit of onion and salad into a roll and drizzled with lemon juice. Such a simple pleasure, yet amazing. For the true experience, buy a glass of pickles from one of the pickle vendors, and enjoy your fish sandwiches with the pickles and their juice.
I had a döner kebab at Dönerci Şahin Usta in the first Istanbul episode of my show, you can watch it here.
