Balik Ekmek. Fish Bread. Simple and direct. And very popular. There are fish sandwich places all over the city, but the most popular ones seem to be gathered near the Karaköy fish market at the Galata Bridge. You might think that all of the fishermen on the bridge or along the banks of the Bosphorus and Golden Horn would mean the fish in these sandwiches was very fresh. But you'd be wrong. Most of it, we're told, is frozen and comes from Norway. Whatever. For five Turkish lira ($2.10), it tastes mighty good and no one's complaining.
