Trip Advisor has great restaurant ratings. I think it's tripadvisor.com, then look for the city you want and then restaurants. It rates restaurants 1 to ever how many -- we've found some great places that we probably wouldn't have went to when we were in strange cities on trip advisor.
Don't see any violation of the rules here ~ actually, it's a good use of the board to ask for advice from around the country which is one of the reasons why all of us come here ~ to get some ideas on things we don't know on our own!
I agree with Linderhof about tripadvisor.com. I'm a member and use it often when we are traveling. Have also heard good things about YELP but have no personal experience with them. Have fun choosing one!
