I see corn dogs listed for $4.25 at the Egg Roll Wagon in Adventureland. Near Aladdin ride. The wagon is not always open, depending on season/crowds? I have seen corn dog nuggets listed on the menu at Casey's on Main St.
In May they were $3.50 and they are between LTT and Peco Bills. THey also have them at the Egg Roll stand in Adventureland in front of the Alladin ride and they are $4.25 which is weird because they are the same thing and the same size
