Love this place, but never take my kids. They are picky eaters and I could never justify the cost. The one closest to me is 45 and 1/2 price for kids.
I think kids under 6 are free, but the whole dining experience can take a long time and I know my kids at that age would not have allowed me to have an enjoyable time. When I'm spending this much money, I want to enjoy and savor the food. Of course, I also have nearby free babysitting for these occasions, so I am biased.
