Integral Yoga books is a good place to go if you're: a) a vegetarian b) a Yuppie/Hippie c) a health nut or d) looking for interesting company and conversation. The people there are incredibly nice, and are willing to talk about anything for long periods of time.
They have tons of books concerning health, vegetarianism and related topics. I've been there twice and found it "enlightening" both times.
