We just ate there for breakfast and dinner on our Christmas trip. FANTASTIC. They had the best eggs I have had anywhere in Disney (well, except for the truffled egg at Victoria and alberts-to die for!) Anyway, they were so good. They had a big selection too. They even had a yogurt bar with granola, etc. I liked that.
We had been there for dinner before so we knew how great it was. One of the things I like best on their buffet at dinner is the salads. Sounds odd, but I really like most of the salads up there! the seafood is good and they also have a great selection of traditional foods like ribs/green beans/mashed potatoes, etc. for the non seafood lover.
My only suggestion is to not get the 5:30 seating. That is right when they are opening and both times we have been there at that time, the line has been long and the buffet line is even longer. We actually booked this time at 6:00 and it was ok. It allowed everyone to get through the line and get over the initial excitement of going to a buffet.
Oh, and teh character interaction at breakfast was great. They aren't super crowded so it gave them an oporunity to spend more time at our table if we wanted it.
