We were there last Thursday, 5/1. It was a much anticipated dinner, as my DGD5 adores Cinderella. The Stepmother and Stepsisters were a hoot! One of many favorite moments -- after Lady Tremaine (Stepmother) interacted with DGD for a few minutes, she was done and said (imperiously), "Now sit child!". My granddaughter immediately dropped to the floor at her feet, plop! This from a child that has never listened to her parents in her life! Lady Tremaine had to tell her "On your chair, child!"
So it was great fun, and a must do if your child loves the characters.
That said, the food was indeed mediocre at best. We sampled various things, ranging from OK to not so OK. The prime rib was nicely medium rare, but both mine and DW's prime rib were easily half fat -- great bit gobs of fat. Yuck.
So I recommend it, but just for the characters, not the food.
