Geolocation services like FourSquare, Gowalla and Whrrl allow us to cross reference to find friends cross platform. But as far as I know Yelp doesn't do this.

The last time I tweeted something about Yelp, I got a few friends to reach out to connect to me there. I like that. Most of my current Yelp friends are Yelpers with very little other social media activity. This does not make them lesser people but it does mean I haven't gotten to know them well.

My recent find - Sushi on La Cienega opened about 2 months ago. They don't have a liquor license yet but I highly recommend them.
