Berardi's potato skin fries

Hi,
I have a regular who comes to my hot dog cart. He often talks about when he was a kid. He lived in Sandusky Ohio. He states that at a place called Cedar Point there used to be a place that sold a paper cone full of french fries. He states they were the best fries in the world, and were served with...believe it or not, white vinegar. I thought this rather odd.
I was curious if anyone has a recipe for these types of fries. It sounded like they were heaven sent. Anyone have in input ? I guess the Berardi family cut ties with Cedar Point, but opened Berardi's family resturant instead. THey do appear on Hollyeats.
Thanks
