If you're an Iron Chef fan, you'll probably want to read this; if not, you probably won't. It's a quick, momentarily diverting read, with lots of photos.
On the bright side, it includes a list of all the battles. It doesn't however, say who won (presumably so as not to give away the end for those who haven't seen a given episode yet), and I would have appreciated even a one-sentence summary giving a highlight from each episode, but I suppose that would've required too much effort. Also, there are a bunch of photos of various dishes made on the show, but in most cases, they're unaccompanied by actual recipes. Maybe those who are into epicurean eye candy will appreciate this; I didn't.
On the other hand, this book was originally written in Japanese, and some of the translations are, well, kinda charming. "This program is too demanding so I hope it stays in an eternal sleep," says Kenji Fukui, for instance. Love it.
Anyway. It's got profiles of the Chefs and others associated with the program, a history of the show, various highlights, and lots of photos. So, again, if you like the show, it's worth a read.
