I have had good a success rate (~ 70%) at restaurants that were based on yelp reviews. Also, I have had good success rate trying dishes that were highly recommended by many reviewers. Although I agree that there are a lot of morons on it that pretend to be real food critics, that is pretty much the case with any review site. The trick is to try and gauge a really good review from total tripe, and as always, take everything with a grain of salt. But why go through such a headache when there are perfectly fine and experienced critics that will give you an unbiased, well documented review of the dining experience at that establishment. Especially, if you tend to like a specific critic's taste and passed reviews, it gives even more comfort in the relevance of his other reviews to you. I know I will like any place well rated by Bruni or Platt, without a doubt.
