We've eaten at every buffet, many, many times and there are some bad buffets:
Chef Mickeys - noisy, crowded, broken ice cream machines, dirty, subpar food and subpar service
Hollywood & Vine - subpar service and food, characters are ok
Boma - horrible service and very noisy, but food is very interesting and beautifully laid out
Princess Storybook Dining - grossly overpriced, yucky food, subpar service and very crowded
We are starting to phase out buffets this trip, as most of them have seriously gone downhill the last few years. That being said, here are our favs:
1900 Park Fare - breakfast or dinner is good food, nice atmosphere, good service and great characters
Cape May - good food, great characters and service
Donalds - vastly improved over old buffet: good food, great characters, fun parade and good service
Crystal Palace - great atmosphere, good food, great service and awesome characters
We have also done Garden Grove, and it's ok (service and characters were horrible), Trail's End was ok, but too crowded (food has since changed recently) and we like Maya Grill for a nice brunch buffet too.
HTH! Happy eating, Tiger
