(Prairie du Chien, Wisconsin)
At this summer-only burger stand, founded by a fireman in 1909, Motz says he's found the most unusual method for cooking a burger he's ever seen: "They poach the burger in water, surrounded by onions." While the thought of boiled beef is depressing, Motz says the burgers come out wonderfully and are actually infused with onion flavor. They're served on a locally made bun with horseradish mustard, but don't bother asking for cheese – the only option is whether you want one 'with' or 'without' (that's onions on top). "Pete's is only open for a few hours a day on summer weekends," says Motz. "But it's definitely worth waiting for."
