When famed fine-dining restaurateur Danny Meyer opened a hot dog cart in New York City’s Madison Square Park in 2001, the venture drew legions of customers curious to experience Meyer’s take on all-American street food. The curious became the committed and Meyer’s little experiment acquired a permanent structure in the park – the Shake Shack. The Shack regularly drew long lines, leading Meyer to build a company around the concept. In a few years, Shake Shack expanded to a chain of burger restaurants in the United States and licensed outlets internationally.
