i've never had checkers, and i've never had white castle.. but i like the mushroom and swiss burgers at fuddruckers.. =) and they have the nacho cheese sauce, so I turn my fries into cheese fries there... i hate wendys fries, and i'm not the biggest fan of mcdonalds fries, but i lurve burger king fries, and chick-fil-a's fries are pretty good too...
