Smashburger.

Smashburger isn't just the name—it's the way chefs grill every burger. First, they form never-frozen, 100% Angus beef into a giant meatball. Then they season it, place it on a butter-glazed grill, and smash it into a patty. The process caramelizes the beef, locking in flavor while keeping the meat juicy and tender. The chefs then sandwich each slab in an artisan bun and turn it into one of an array of standard burgers or locally inspired specialties unique to each market. This handcrafting approach typifies everything else the chefs do, from blending handspun Häagen-Dazs shakes to hand painting Smashburger's logo onto every beverage cup. Letting its food stand for itself and relying mostly on word of mouth for advertising, the Smashburger franchise expanded to 160 restaurants in five years, with its swift growth from zero to 100 stores making it one of the nation's fastest-growing restaurant companies. This rapid development even caught the attention of Forbes and Inc. along the way.
