Reads like a good cook book
I'd read this even if I weren't traveling anywhere. The fact it doubles as the most practical guide I've taken on a trip is almost beside the point.

Knowing something about what I was eating meant I could talk to people about it. The service we got was noticeably warmer as a result.
Saved me a week of research
I'd normally spend evenings before a trip reading blogs and cross-referencing lists. This replaced the whole ritual and did it better.
