Seriously, Everybody I know uses Yelp before they go anywhere.
I'm not sure about other places but I know here in the Central Coast (Monterey area) and Palo Alto, all of my friends and myself have used this site for years. It doesn't matter what the service is. Of course, most commonly for food and entertainment, but even outside the box when you see that doctor on the road while you are traveling or you need a recommendation for a handyman. This company has more pull than the shorts give it credit for. I'm just surprised we didn't see a move like this last year.
