The last time I was there (a week ago) there were a couple kids under 12 there, with their parents, and a rather large group. I believe that the rule, as written on the wall, is: "Be good, or be gone." So, as long as they are well behaved, I believe they are allowed.
It's a bar?
As long as they're 21, yes.
