The one restaurant I remember from the last time I was at WDW at the age of 5 was The Land. I remember loving Mickey and Chip and Dale coming to the table a lot.
My top one is Journey Into Imagination with Figment. Then comes in no special order Dumbo, It's A Small World, Winnie The Pooh, and The Barnstormer. Take in mind the last time I was at WDW I was 5 years old.
