Kitchen Confidential and Medium Raw by Anthony Bourdain.

The Bullpen Gospels by Dirk Hayhurst - yes, it's baseball, but you'd hardly notice it. ;) Lots of fun and a really great writing style. He's got Out of My League about playing for the Jays coming out in February.

And John Birmingham also writes amazing non-fiction. Leviathan is a brilliant history of Sydney, and Dopeland is about marijuana culture across Australia, both excellent reads.
