When we went to WDW in 03, we did both places. The did Crystal Palace on one day for breakfast and Chef Mickey's on another day for breakfast. The reason we chose the breakfast meals is because of my mom's pickiness of food. At least with breakfast, there is always something that she will eat. Anyway, we didn't have kids with us, just two adults, and I have to say that at Crystal Palace, the Pooh and his friends interacted with us as much as, if not more, as they did with the families and their children. Tigger messing up my mom's hair and THEN trying to straighten it back up was THE BEST! We had a wonderful wait person! We never saw the bottom of our juice glasses!
On another day we went to Chef Mickey's. The food was okay, but I didn't care for the set up of the restaurant. It seemed very congested for the space that it was in. The food was good and some of the characters were very interacting with the guests. Goofy must have been having a bad day, because he didn't seem very friendly. Chip and Dale were great though, as well as Pluto who skipped me out the door when we got up to leave. Mickey and Minnie were great too.
My choice would have to be Crystal Palace. When we go back to WDW next July, that's one of the places were definately returning to!
