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.
They ask what kind of tea I want - black, green etc and bring a cup of it together with sugar so I can add it to the tea if I want.
Europe.
Can confirm for Switzerland. It’ll probably be some crappy tea bag quality, like lipton yellow or Twinings. They’ll also probably charge you 4-6 CHF (about the same in USD) for it.
Same, although it’ll probably be served in a little teacup (about 2 cup’s worth) with a generic teabag in it. There may be a small pot of hot water on the side.
(Europe as well)
In the better restaurants and cafes they will bring you a cup of boiled water and a box of different kinds of tea bags from which you can pick one. (The Netherlands)
I would say, good restaurants and cafes do not serve tea in bags :) but this is already details, anyway you get a tea, not a soda called “ice tea”.
Which country?
This can vary wildly per European country, after all.
Germany, Austria, Sweden, Niederlande etc.
Excuse me what did you just call us?
Nah, I jest.
In all seriousness, thanks for adding the list.
I swear it’s not me, it’s my smartphone. We will have a serious conversation with it about this!
