We've been to Cape May 3 times or so and it is one of our favorite places at disney. The crab legs are amazing and the decor is cute. Also love the oreo bon-bons. If you like seafood you will love this place.
Here is another thread you might be interested in:
We've had dinner at Cape May both in November 2009 and 2010. The first trip, we absolutely LOVED everything. Service and food were excellent. 2010 trip was not the best. Our server was rude, and he put 5 of us in a cramped corner table for 4! The food was just average though too. Maybe it was just an off night for everyone?
Hope so b/c we made another reservation for June that I'm wondering about.
Good luck to you. I hope you have a great time.
