Have you tried a book called Hungry? No, really, that's it's name. It's no Jonathan Gold, but it's written by a bunch of different people and suggestions are pretty much on the mark. It looks like a Zagat book, but is lime green instead.
It is supposed to come out in November. I called around and no bookstores have it in stock yet. Apparently, the "November" release date means it could take up till the end of the month to be on shelves.
