I'm in the "it's gross and we won't go again" camp. We've been to several buffets and found this one the worst. And we've gone for both breakfast and dinner, each a couple times, thinking we might have just had off nights. But, no, it was the same each time.
What I saw was just a total lack of control! For some reason, more than the other places, kids are given free reign and parents don't supervise. So at the buffet I've seen kids reach into the food with their bare hands--and then drop it back in. All the food gets mixed into other things and strewn all about the buffet. And the floors??? EWWWW. There's enough food on the floors to feed my family! I understand kids spill. But this is beyond that! Just food thrown everywhere, under all the tables, around the buffet, etc.
If you want a good breakfast, characters and cleanliness, check out Tusker House at Animal Kingdom. You get to see Mickey, Donald, Daisy, and Goofy and the food is much, much better. Atmosphere is great.
