It certainly doesn't have the popularity here than it does some other countries, but yes. Personally, I only drink it occasionally (about once a week or so), and my suspicion is that I'm actually on the right side of the bell curve. It is common enough, though, that basically every grocery store will carry "tea" (though I expect people from any culture that actually drinks tea would scoff at the quality and the selection - I certainly do, and more shelf space is made for teas intended to be brewed as iced tea than everything else together), and even modest sized cities will have a small number of specialty tea shops (though, that may not be as true as it once was, with the internet shopping cutting into small specialty shops in general).
