I have eaten there twice. It is a pretty good buffet and the cheapest Fantasmic package dinner. We did the package last May with H&V. I can always find enough food to fill me up on that buffet. I sometimes find myself at the kids buffet getting mac and cheese.
I haven't tried Mama Melrose, but that is on my list for the next package. I love italian.
I have eaten at Brown Derby, but wouldn't want to spend that money when I have two other options.
