It's different than CRT. First, it is a buffet, and while the food was hot tasty and there was planty of options to choose from, it is still a buffet.
I thought that the character interaction was really good, althought Charming is a bore IMO. If you plan to engage the characters you will have a blast because they truely are hysterical. Lady Tremain commisserated with me about raising girls, and did so while sneering at my Tweenage DGD, and sniffing at the two little Princesses with us. The sisters had plenty to say, and Cindy was very sweet. Proper but sweet.
The meal takes time because the characters do take time at ecery table and it is a large restaurant.
We generally do not feel rushed at character meals though, so I ope your experience at CRT was an anomaly.
