Personally, I love Cindy's. Sometimes in the morning I will tell DH in a voice of dread and dispair, "There are people eating right now in my castle," lol. I also like Cindy's before the MK opens for that not so crowded stroll up Main Street, but for that I could do Crystal Palace, too.
My daughter likes princesses, but she likes other characters, too. She has been there twice, and wants to do Donald's next.
Dh is not a breakfast eater, so to him it makes no difference.
As for the food, I only really enjoy the potatoes and the stuffed french toast. I think for us it is kind of getting to be a "been there, done that" type of thing. I am sure we will do it again, but maybe not in our next couple of trips.
***Edited to add***Gustav is our FAV waiter, and the price is worth it to see him alone!
