I have only had breakfast at Chef Mickey's, but I don't think we will ever go back unless one of my girls specifically request it and I cannot talk them out of it. I love the characters they have there, but they were very rushed compared to the many other character meals we have done. The food was the worst of the character breakfasts we have tried (6 different ones). I would eat here if you really want to have a meal with these particular characters. Otherwise, I would go elsewhere. You can find many of them at other meals.
We did 1900 Park Fare for the first time a couple of weeks ago. I am a very picky eater and so are my girls, but we all found more than enough food to satisfy ourselves - and then some. The characters (Cinderella, Prince Charming, the Stepmother and Step Sisters) here are wonderful! We were seated in an area where we were the 3rd table to see each character after they were announced, so we went though the characters very quickly and very early on in our meal. We were finished with characters, and basically finished with our food in about 50 minutes or so, but we didn't leave for at least another 30 minutes because we had so much fun watching the characters interact with everyone.
My girls (4/8) are very shy, but they absolutely loved the characters here. My DD4 even got up (upon her request) to dance with Cinderella. They also do a little fun "parade" thing around the restaurant and DD4 loved the step sisters so much she got up and did that on her own. She usually asks her big sis to go with her but she didn't care here. This place is a definite must do on our future trips!
