There’s a great little pub here in CT that lists "Soggy Fries" on the menu….shoestrings SOAKED in a rich brown gravy and then covered with melted cheddar. They should accompany that dish with a coupon for an angioplasty.
One of my personal favorites for my fries is a mixture of ketchup and yellow mustard. I get weird looks for that. (Though I get even weirder looks when I ask for sauerkraut on my cheeseburgers!)
