You may want to check out the buffet restaurant at Gaylord Palms. They have a revolving menu of Italian, Spanish, Greek and Moroccan cuisine. The person I spoke with there said that seafood is always on the buffet, as is prime rib, regardless of the other selections.
It is set up in separate stations and is a very lovely Spanish style restaurant.
I believe the cost is about $24 per person except for Sunday brunch which is a bit more $28 (?).
If you want just clams, mussels, fish, and shrimp (with crab legs extra) Cape May is about $24 per person, drinks not included.
I avoid Angel's, and Boston Lobster Feast.
