IMHO Chef Mickey's for dinner is one of the best character meals as far as value for your money. We are not big breakfast eaters so we tend not to do the breakfast character meals.
We have eaten at Chef Mickey's for dinner at least 5 times and LOVE IT!! They have a special "kid's bar" with pizza, hotdog bites, mac-n-cheese, french fries,etc... as well as a huge selection of adult buffet favorites including peel 'n eat cold boiled shrimp. The desert selection is very large and there is a special desert for kids--Goofy will help them decorate their own cupcake(great photo op!).
At set intervals throughout the evening the waiters get the party going by singing and waving their napkins(everyone is invited to join in) and then the characters come around for autographs and photo ops.
The food is good and great for families with large appetites (my 14 year old nephews will eat their weight at the buffet this October!!). Also I have never felt "rushed out" here as I have at other character meals.
