Before we cross the Bosphorus Strait to Asia, this story starts on Istanbul’s European side, at a small stand that has been operating in Beyoğlu since the mid-1970s. There, Muammer usta serves up expertly-cooked and sliced cuts of kelle söğüş (chilled lamb's head meat), perched in a strategic location across from the local fish market and a stone's throw from the Nevizade strip of meyhanes and bars. Over the decades, Muammer usta has become one of the most recognizable characters in the area. The usta’s influence cannot be overstated. His stand is beloved by locals, foreign tourists from across the globe and food critics alike.
