Most of you may already be aware of today's link, but I thought I'd throw it up there anyway, in case it helps someone.
Citysearch is a nationwide online restaurant and activities guide, which lists reviews and rankings for businesses in most of the nation's metropolitan areas.
Each year they have their own categories for which they produce top ten lists (mostly for restaurants) and people can vote on their favorite BBQ place or burger joint. Those lists are a good resource if you're looking for places to try. I know we check out a city's lists if we're going to visit on vacation.
