Want to get a Bourdain book. Any recommendations? Is it only about cooking/travel?

I admit, I don't know much about Anthony Bourdain. From cultural osmosis, I gather he's a cook, but also a travel writer, and apparently is viewed as a well respected thinker?

If someone isn't interested in cooking or travel, does his books pierce through and provide any philosophical insights/guidance, or do you have to be interested in those topics to make it worth reading?
