I was thinking of getting the Chez Panisse book, because my parents treated my then-fiance and me to a meal there last year, and it was outstanding. However, from what I've read online, it isn't the greatest cookbook out there, and I've read a surprising amount of "I'm so disappointed, some of this stuff is average or mediocre" kind of reviews.
I'm just wondering which restaurant books Chow feels is worth it? I have the Zuni Cafe book, and I love it, and for more than just the roasted chicken and bread salad! ;D I also use the Rose Bakery tome pretty often. (Entitled "Breakfast, Lunch, Tea: The Many Little Meals of Rose Bakery.") I'm considering investing in a copy of the Bouchon Bakery book as well, based on a lone macaron someone brought me from there a while back. It was unforgettable!
