Anything except durian.

As for Rick Steves, he's amusing. He caters to his target market very well. Even the well-heeled traveler can make fine use of his books if heading to a new region for a brief period when the competition caters to young party types and I find often leaves out important details. The HD video from his more modern shows is quite nice to see.

Also - pay attention to how often he refers to things as "evocative" in his shows.
