We did both last year. I liked them both, loved the atmosphere, at Cape May, although they stuck is in a side room, but the food had more variety at Chef Mickey's. I don't even thick they had waffles at Cape May.
I think at Cape May the characters could spend a little more time than at Chef Mickey's but honestly the interaction was good at both, they gave us signatures and photos etc.
We are Minnie fans, which is why we did both
OH, at Cape May, Minnie is in Beach attire, so if you want the red polka dots than do Chef Mickey
