Kopp's Frozen Custard
Known for its butter-burgers and frozen custard, Kopp's is so Midwestern it hurts. The Milwaukee chain serves wide, jumbo burgers that range from a single-patty hamburger to a double cheeseburger -- and it goes without saying that the double cheeseburger is the way to go. Two thin patties are covered with thick layers of Wisco-made American cheese, topped with relish in lieu of pickles, and sandwiched between a well-toasted bun. The custard is as creamy as the burgers are juicy, doled out fountain-style in flavors like banana, hot fudge, marshmallow, and butterscotch.
