I can't think of another dinner buffet that has more seafood than Cape May. A couple of them have peel n' eat shrimp or maybe mussels, but none others are strictly seafood buffets.
Cape May used to be a favorite of mine, but quality has gone down in the past few years and it has gotten so crowded that you have to wait in a 15 minute line for your food, which is annoying.
You can get crab legs, I think, but you pay extra for them!
