Be aware that 1900 Park Fare is currently undergoing rehab and during the rehab the character meals are being held in the GF Cafe. During this time, rather than a buffet, the food is pre-plated. Rehab is scheduled through October 1.
As for 1900 Park Fare under normal operating circumstances, I think it's the best breakfast buffet on property. Great variety of foods, always hot and fresh (at least when we've been, and we've had seating times at 8 am and 11 am), omlettes made to order, the strawberry soup is to die for.....I could go on. I also like the characters. They have a lot of "face characters" (Alice, Mary, Mad Hatter) and they are a lot of fun to converse and interact with. The Mad Hatter is a hoot.
The dinner buffet is excellent as well.
