Breakfast is delicious! Have done it 4 times and always had great food, service, atmosphere. As pp said, if you make an ADR before the park opens, you get great pictures of an almost empty MK.
We had dinner there once, and will never do so again. Food and service were terrible.
or lunch.... Crystal Palace is probably our most favorite buffet on WDW Property. The menu is phenomenal and a pleaser for all types of eaters - adult and children. We actually have ADRs at Tony's Town Square and DH is pushing to change it to CP!! Not to mention after a long day on your feet walking around MK, its nice to sit and eat a meal in an air conditioned restaurant! Our youngest is almost too old for the pooh characters but the food and atmosphere is well worth it! You wont be disappointed!
My favorite buffet Atmosphere and food are awesome... but I will say that breakfast food is great at any character meal so I would do dinner at CP. Dinners can be disappointing some places but CP really does a lovely job. We do it when MK has evening EMH and it works out great. Enjoy!
Dinner! Sad to say that Pooh and his friends are our least favorite characters, BUT we manage to eat there every year MMMMMM! The food is so good. Something for everyone and very flavorful for a buffet can't wait until April to do it again
