The idea behind this Open Directory is that everyone can add reviews of restaurants, link to reviews published elsewhere, and generally share good information about the restaurants you might choose for the evening. There are thousands of restaurants listed. Look for your favorite.
Full Disclosure: I've just volunteered to help edit for Chicago for the site, but haven't received a reply yet. I've also submitted links to our reviews at the site so you may see them pop up in the next few weeks.
