Dole whip float, frozen lemonade (dairy sensitivity so no Mickey ice cream or that would be on this list instead), giant Mickey head pretzel, any confection that strikes me at the moment at Les Halles bakery at France in Epcot, home made caramel popcorn at Germany in Epcot (not the prepackaged stuff but the fresh one they make there and keep behind the counter).
The sweet cream cheese stuffed pretzel at Lunching Pad would have topped my list, but sadly is no more. That was always my first snack stop on my first MK day for every trip. Time to find a new tradition.
