We went there a couple of years ago with our two DD's, 7 and 8 at the time. I myself really enjoyed it. It was my type of food, I like BBQ and the simple things that go with it. Plus I'm from Iowa so I felt at home. Somewhat spendy for the quality of food, but it was good.
You have to get there early to get a good seat. The lines start forming very early even with PS, this just guarantees you in the gate otherwise it is run for a seat. I thought it was rather unorganized, but a very good time.
Kids and DW had fun with the characters and line dancing. Go ahead and enjoy it....
