Chonch fritters and chonch salad in Key West, Florida.... yum!
Doner kabobs always made me cringe - there was a party of pioneers that tried to cross the Rocky Mountains in the 19th century named Donner, and they had to resort to eating their dead companions to survive. I just can't bring myself to eat Doner kabobs!
I did have an odd but very tasty meal at a Highland Games in Scotland - Ostrich burger (with onions) and chips with green curry sauce on them... yum!
Elephant ears at any American fair

- covered with melted chocolate and powdered sugar.
Fish & chips just about anywhere in the UK - but they aren't allowed to serve them with newspaper anymore
"The Queen's Apples" at my local renaissance festival (Hoggetown Medieval Fair, Gainesville, FL). Take a green apple, slice and core, cover in homemade butter caramel sauce, whipped cream, nuts and a cherry... heaven!
Forgot to say - their booth is usually right next to the roasted nuts booth. "The King's Nuts"
