In the South East, they bring you sweetened (usually far too sweetened for my tastes) iced tea. This is amazingly universal.
I live in NC and have been probing the border for years.
For “nicer” restaurants, the universal sweet tea boundary seems to be precisely at the NC/VA border.
I used to live near a cafe that did Turkish coffee, your comment has made me realise how much I miss that place. I live in a big city now, I can probably find a new place
