Definitely hit Cape May for crab legs, there's also a large almost old fashioned coffee thermos thing of drawn butter for them. The oreo bonbons are also to die for. I'm not a seafood person at all, but still found lots of stuff to eat.
I also went to Garden Grill...and had mixed feelings. It's not a huge place which I enjoyed, but the slow rotation of the restaurant made me dizzy. I have some balance/fainting issues, and I really feel that this is why I was so effected by the rotation. The character interaction was great, Chip was amazing with us. We had already met him and he saw my friend massaging her temples (big migraine starting), and she looked over my shoulder and there's Chip, massaging his temples too. He just started doing all these crazy sight gags by the stairs and this went on for like 5 minutes and we were dying laughing. Best character interaction I've ever had. The food was good, not great but I've had worse. It's a nice kind of homey, fresh feel to the food.
I've never been to the other places so I can't weigh in there.
