For visitors to Hanoi, I offer the following words of advice:

Advice #1: When at a restaurant, ask to use the restroom (WC) first, because it will usually involve you going through the kitchen, which you can then scope out.
Advice #2: Ignore Advice #1, or you'll go hungry.

Actually, we found what seems to be a rather nice travel cafe, that seems to go all the others one better -- HandSpan travel. Clean, spacious, and friendly. And with full-sized seats -- nearly everywhere in town uses kindergarten-sized chairs, for some reason. Must have something to do with the fact that squatting seems to be the official Vietnamese stance (and I'm not just talking about the toilets). For some reason, you see people squatting around everywhere.

We've decreed today to be Casual Day. We're off to do some more casual things.
