3. Juicy Lucy
WHERE IT'S FROM: Minnesota
THE SKINNY: In true Midwestern fashion, this here burger is stuffed with molten cheese, probably very politely. Two bars in Minneapolis (Matt's Bar and the 5-8 Club) both claim to have invented it. As long as the pair keeps those cheesy patties coming out hot and gooey, we're staying out of it. (Unless one of them starts calling their city "the Mini Apple," then we'll take sides.)
4. Butter burger
WHERE IT'S FROM: North Midwest US.
THE SKINNY: Unsurprisingly, butter is a main patty ingredient, unless it's spared until the end, when a big chunk of butter is left to melt atop the patty.
WHERE IT'S FROM: Colorado.
THE SKINNY: This burger comes well-soaked in either red chili, green chili, or chili sauce, and topped with white onions and french fries. Unlike NY pizza, it's no crime to eat this treat with a fork and knife. Additionally, this spicy foodstuff starred in a Travel Channel show called Food Wars (of course), in which five restaurants from Pueblo, CO (where the S-b was invented in the '70s) competed to determine who served the top Slopper.
