I find Yelp (and TripAdvisor) useful in small cities that Chowhound wouldn't be covering, at least more useful than the typical front desk clerk at the random HIX where I'm staying that night. In these types of situations, I'm just looking for "better than Ruby Tuesday" and I can usually piece together enough information to get down to two or three places, and then check their websites and maybe drive by them. But I tend to look at "most reviewed" and don't really differentiate between what gets an average of 4.1* vs. 4.3*.
