Instagram-worthiness aside, Martina has become a burger destination in Minneapolis. Their sought-after double cheeseburger is only available on their brunch menu, so if you're a fellow Martina burger seeker, keep that in mind. Martina's masterpiece is made of two patties, American cheese, and sliced pickles. Red onion, lettuce, and tomato come on the side, but this is one burger we like to keep pure. No vegetables, please. Melty cheese, tangy pickles, and a perfectly toasted bun will do.
