In the end,
Do you want Mickey, Goofy, Chip N Dale, Pluto, and sometimes Minnie and Donald in the concourse of the contemporary with soaring ceilings and a view of the monorail or do you want Pooh, Tigger, eeyore, and sometimes Piglet in a conservatory with a pretty garden in the middle of it?
From what I've seen here and in guides and on other sites, there really won't be all that much difference in the food and what difference there is is luck of the draw.
Both run 80 thumbs up, 20 thumbs down in the UG.
Both are buffets so the menu changes.
Sometimes one is better, more deluxe, etc, sometimes the other. Both have loyal followings and both have detractors.
