Query: Moon Mexico -- a fine guide, indeed.

I used the guide in 2000 and found it quite solid. Everything mentioned in it was there, and I generally agreed with the assessments.I like Moon Guides because they strike a practical balance between high-brow analysis of, say, the Blue Guides and cultural vacuum of Fodors. If you like to decide for yourself where to go, this one is a good start.
