Chef Mickeys is the most popular. 'Ohana and Cape May Cafe have similar characters, 1900 Park Fare has Mary Poppins, Pooh, etc., and then of course you have the princesses and Crystal Palace. So I guess it depends on what characters you want to see. My pick would be Crystal Palace, but I have heard Cape May is very relaxed, inexpensive and good character interaction if you want to visit the Beach Club.
