There are plenty of good options for Southeastern Anatolian food. You may try Papatya Restaurant int the city center for kebab and other red meat/chicken food. However do not forget to eat fish at the restaurants in the shore of the Atatürk Dam Baraj as called in Kahta. Especially Zeynel'in Yeri is good choice. Fish from the dam itself and from Kahta river should be tried. Yayın a fatty freshwater fish and Sarıgöz are pretty delicious fish. These restaurants also serve alcoholic drinks, including raki which is a good company with fish.
