When we were there in late August, I believe it was a scoop of vanilla ice cream with chocolate or butterscotch sauce. DS doesn't like sauce, so he had a plain scoop of vanilla ice cream.
I will say, this was the longest meal of our trip, with the slowest service. We also were not overly fond of the food, other than dessert. DS is 9, and it took too long for him.
I wouldn't recommend this after a long day of doing things, but if you arrive well-rested, you might enjoy it more.
