"Shake Shack started as a seasonal stand in Madison Square Park in 2001. Two decades later, it has more than 400 locations scattered across the globe. It’s the rare example of a chain that’s managed to keep up quality while expanding rapidly. Lettuce, tomato, American cheese, and a squirt of Shack Sauce serve as supporting roles for one of New York’s most popular smash burgers. What these patties lack in char, they make up for in size: You’d be hard-pressed to find a burger with more beef for under $10." - Luke Fortney, Robert Sietsema
