I saw pic's of 'em once....looked like fries with chopped lettuce and tomatoes on them! Kinda like nachos but with fries!! Just troll thru the food porn, eventually you'll come across a picture!
They are fries topped with cheese sauce, ranch dressing, bacon, lettuce, and tomatoes. You can get them at Pinocchio Village Haus. I discovered them during my 2006 trip, and have had to have them once every trip since.
