Apart from nargilas, you can drink there delicious menengiç kahvesi, which is a very sweet milk based drink, a local speciality. The Tigris also has European style toilets available if you should be desperate.
There are many teagardens in Ofis and along the Basalt city walls, where you can meet locals. People in Diyarbakir are very open towards foreigners and you'll have a hard time paying for your own tea.
