Hello shipwrekkt, welcome aboard and hope you like the site.
I've lived in several Wisconsin cities, and can say that "pizza fries" or otherwise known as "cheese fries" do occasionally pop up on menus here, mainly in pizza joints. They are not everywhere, but found often enough to be well known.
I never did understand why the name included the word "fries," because basically a serving looks like a cheese pizza, cut in elongated strips, and then one center cut the other way to create long thin pieces easy to pick up and eat.
Can't show you a picture, as trying to google both "cheese fries" and "pizza fries" only brings up the potato variety.
But there is a recent thread here about "Quad City" pizza, with a picture, in which the cuts are similar.
Just as info, here is a menu and review for a place I enjoyed, Springville Wharf
in Stevens Point WI
. For the review, you will see everyone really enjoyed them, and they call them "cheese fries" here. For the menu, scroll all the way to the bottom, where they are the last entry, and described as the house specialty.
And they are served with marinara, and here they even offer them without cheese, crust only, I guess, never tried that. Maybe there would be seasonings included. http://www.urbanspoon.com/cities/322-wisconsin/restaurants/1320709-springville-wharf-restaurant/menu http://www.tripadvisor.co...-Plover_Wisconsin.html
I always liked them, but they do seem pretty much like a real good cheese pizza.
And I'll bet they are quite like your garlic fingers. Garlic cheese bread is easy to find here too, and of course breadsticks without cheese.
