Just had breakfast there last week - it was a CS on the DDP. The buffet was fresh and good quality - all traditional breakfast items and baked goods plus fresh fruit, yogurt and made to order omelets. It was a great use of a DDP CS credit or if you are a big breakfast eater I think it is a fair price out of pocket considering you are at Disney.
It is still a CS buffet for breakfast and lunch. Dinner is a CS a la carte like a typical restaurant.
In the CSR thread in the Resorts section, you will find some reviews on the buffet. It seems as though the lunch buffet is preferred, but I think I would like breakfast more. I may (undecided thus far) be trying the breakfast buffet there during my trip in 11 days and will report back if I do.
