My 2-3 experiences with choosing "Zagat rated" places were not particularly good. Three years ago I chose a rated restaurant in Philly and took friends there only to find the place had shut down (the Zagat sticker was still on the front door). A couple of times in NYC, I found Zagat rated restaurants to be mediocre. In general, I'm not convinced about these rating organizations, including Yelp. Maybe Google can improve it.
