Hoşgeldiniz and welcome to Little Istanbul! Each Tuesday and Friday, Maybachufer is transformed into an open-air bazaar where everything from vegetables to meat and fish to housewares and fabrics is available for purchase. Haggling is permitted, and just before closing time you can get some good deals. It’s liveliest and the most pleasant in the summer when Kreuzberg’s hippies play music and carry on at the far end.
