Never been to Gulliver's but have eaten at Cape May several time, the last time this past Oct. 27th, our anniversary. We love the dinner buffet at Cape May. It is not a character buffet, but it is very good. Not just seafood either. We had ribs and there were several other choices as well, there was a pasta dish too. They have a lower buffet section, so kids can reach it. I believe they had mac and cheese and pizza. Maybe hot dogs. The salads are really good. And I remember boiled redskin potatoes and corn on the cob.
Oh, and I think I read somewhere on this site recently that you can get crab legs for an extra charge. I'm not sure about that, though.
Desserts are wonderful. And the servers are great. All in all a very nice experience. I highly recommend it.
