Shocking! NOT... Typical for Disney!
These items have zero relationship to Africa or Asia, the two primary continents represented at AK.
The best thing Disney could do is use the kiosks to sell street foods more in line with those offered in various African and Asian countries.
I heard the change was due to people feeding these items to animals in the park. Churros remain available at all other Disney parks and jalepeno pretzels are still available in Epcot and Blizzard Beach.
