I thought I posted in this thread already. I must have decided my post was spammy and deleted it once I put my mod hat back on ;-)

I've only heard of Meeplace and can't speak to it, but if it's not what you're after I did a few searches like

Wordpress yelp clone
Drupal yelp clone
Joomla yelp clone

And some pretty promising stuff came up. Can't speak from experience though and obviously you're looking for real recommendations. Wish i could help
