I claimed my locations and set up an owner account so that I could get some control over the information. They send me an update weekly like this:

I think it would be a good idea to take the time to control your content. People with “foodie” type personalities really like to surf these rating sites looking for cool places to eat or dishes to try and some assume the role of amateur food critics. Can’t hurt to convey your message to people that like to eat good food! Also, Facebook lists Yelp as a partner site so traffic can flow between the two.
They do offer advertising and Groupon type deals on the site. But unless you are in San Francisco or one of the other cities where they have basically become the local phone book, you can find better avenues to spend your advertising dollars.
Urbanspoon is another “big” site that comes to mind where you can control your message.
