Thats exactly what I do when looking at bars. My favorite bar has tons of bad reviews because people report that everyones an asshole and stuck up, and you have to be a supermodel to get in, and they stood in line hours and were treated poorly. I always click on the yelp photo, and its inevitably a fat ugly fuck. There are still far too many uglies let in, but Im glad the majority are being denied.  With restaurants when peoples top comment is generous portions I know its going to be nasty.
