Do you really think that a country that gave us the deep fried Mars Bar and deep fried pizza wouldn't have done a cheeseburger? (Spoiler: they have.)
Although I will grant them that the deep fried haggis slice is one of the greatest drunk foods ever created.
Oh im sure its been done, ive just never seen it mainstream or in a restaurant.
I mean fried icecream, fish, fries, chicken, snickers, twinkees you can find all over the place. But a fried cheeseburger ?
