Yes, Deep Fried Mars Bars are a delicacy here. I've never had one, they sound really gross to me. Besides, the oil they fry it in isn't vegetarian-friendly. We have a chip shop in St. Andrews, the KFB, that will deep fry anything. And I mean anything. Last year for Raisin Sunday, some poor first year had to ask them to deep fry a sock.
They also have other strange culinary creations including a chocolate pizza. Think pizza dough, cheese and your choice of chocolate on top (snickers, mars bar, toblerone, etc.). Haven't tried that one either.
I like my arteries nice and clean.
