We've only had dinner there ... someone else can weigh in on breakfast.
We've historically felt like it was one of the most consistent buffets on property. The mussels and clams are tasty (if chewy) - I prefer the mussels. Peel 'n eat shrimp are nice and tender - they aren't overcooked like they are in some places.
DW, who just can't manage seafood in any form, has never gone away hungry. There's usually ribs and rotissiere chicken, plenty of veggies, and other goodies.
One down side - other than the Oreo bonbons, the desserts are pretty pedestrian.
I have noted over the years that the service has been really fine, with constantly bussed tables and glasses staying filled.
You may get some dissenting views, but for us - it's a safe, good bet.
