I really liked 1900 Park Fare's breakfast. Very good food, better choices than most buffet breakfasts. There was a lobster eggs benedict that was absolutely delicious. And where else can you get strawberry soup? The strawberry soup was sweet and delicious -- it is Mary Poppins' favorite.
You said the characters didn't matter but I'll tell you the Mad Hatter was very funny. Alice in Wonderland will be there too -- and both are good prep for the new Alice in Wonderland movie coming out (in March?) with Johnny Depp. Mary Popping, Tigger and Pooh were there too.
Never been to Crystal Palace for breakfast but it is a very convenient location for lunch and dinner in Magic Kingdom -- the buffet is very good, lots of choices, and the carved meats were delicious. The cold salads are also very good. Can't beat the salmon. Tigger, Pooh, Eeyore, Piglet.
