No it isn't exactly like New England but it is a very nice buffet. We dine there every trip to WDW (11 so far). We live on the Jersey coast so we too enjoy seafood. I've had good and bad seafood dinners here and in New England.
The food at Cape May is plentiful with buckets of clams and mussels, u peel em shrimp, lots of salads, fish, chicken, ribs, mashed potatos, red bliss potatos, corn on the cob and many other selections. There is also a kids section (all can take from there, also) with mini hot dogs, mac and cheese, etc. There is a big selection of breads, I enjoy the corn bread. The dessert selections are fabulous. There is plenty to eat for everyone at this buffet. `
The seafood is not gourmet but the meal is very enjoyable and filling. My 3 DS's love it, too.
