It's not just unlimited meat, it's unlimited EVERYthing!!!! I LOVE the cole slaw and we get at least 2 (usually 3) bowls of that to share. LOL DBF really likes the beans so we usually get a couple of bowls of those as well.
The kids are invited to participate in the entertainment yes, it's usually very adorable!

And the guitar player/singer will wander and sing as we walks thru the tables, he will stop and sing at tables randomly or if he sees a first visit, birthday, anniversay, engaged or married button.

It's definitely very informal!
