I was at dinner last night with some friends in a Chinese restaurant. One of whom looked at the listing of Beijing style steamed buns, and said,
"I've had those before. They're like the ones in the Vietnamese restaurants, right?"
I looked at her quizzically, and she explained that she was expecting a bowl of vermicelli.
To which I explained that no, this is a Chinese restaurant, and when they said bun, they meant bread (Incidentally, the Vietnamese bún is pronounced with a long U sound - "boon").
