Mezopotamya Cay Bahcesi
0.50 TL for a glass of tea
Open till late (midnight?)
on the main street, towards the end of the city, next to a mosque
An open-air tea garden shaded by trees with a good view of the Mesopotamian plains below though not as wide as you can see near the citadel because of a neighbouring building.
Local tap water is far too chalky to be tasty and may be unsafe to drink. Buy bottled water instead.
