Answer 1

They also have pickelos. I have found different things offered in different states.

They are sold in Oklahoma. They are breaded and deep fried pickles. lol  It sounds gross, but they taste good if you like dill pickles.

Answer 2

not a secret menu, just different items in different regions.
