Love the idea. Rails Rumble a few years ago produced this: http://tablesurfing.com/ which never actually launched, but I was really hoping it would have.

Comments:

Without the "airbnb for food" tagline on the site, nobody would have any idea that this site is anything more than a bad Foodgawker clone. Nothing about it lets users actually do anything other than share pictures.

If that's the goal, make it clear how to do that or let us know when it will be possible.
