Sounds like the place is a big hit! I can't wait to take my two screaming, hyperactive, over-sugar-fed, mannerless children there so that they can run around while we ignore them as we dine.
Seriously....
If you think you don't like it when kids act up in a restaurant, how do you think the parents feel? There's been times when I wanted to become invisible because of how my kids acted and then there's times when people have come to our table to compliment us on how well-behaved they were!
Going out to eat with kids is like a crap shoot. Sometimes you win and sometimes you don't. You think you've taught them manners and discipline, but you can't beat them simply because they whine at the table or get wiggly because the food is taking a while to come to the table or maybe there's not really kid-friendly menu sections for them.
As parents, you do the best you can in those settings and sometimes it means removing the child from the restaurant. Part of teaching them how to behave in public is practicing it - and they're not going to be angels each time.
Maybe kid-friendly restaurants should have a sign that reads: "No Miserable Old Farts"
