I make lots of trips to Half Price Books and I often find decent food books. This time I bought:

the Chez Panisse Pasta, Pizza, Calzone book by Alice Waters - mostly because of the all seasonal pasta ideas.

I also got The Fortune Cookie Chronicles: Adventures in the World of Chinese Food by Jennifer 8 Lee. I read a review and it sounded interesting.

Then of course I found a copy of Rulhman's Ratio my first trip to HPB after I broke down and ordered it from Amazon. I would have saved 5 bucks.
