There's this place in Colorado that makes parmesan-truffle fries, and they're amazing. I do love me some poutine, but the college student in me is ecstatic when french fries and ranch end up in the same place at the same time, especially on top of my cheeseburger. Other than that; any fried potato, any time, anywhere. Especially with garlic.
I grew up in a little western PA town and we couldn't wait for the park to open in the summer so we coud get our fries in a paper cone with vinegar and I love them that way to this day. The park is long closed but my fry habit lives on.
