As another child comment mentions, Shake Shack was designed in a lab to be a franchise monster. The founder of Shake Shack is Danny Meyer, who is quite possibly America's most celebrated restaurateur and the CEO of Union Square Hospitality Group. By the time Shake Shack opened, Meyer had been running restaurants for over 30 years.

The hot dog cart in Madison Park that originated Shake Shack was stocked by the kitchen of Eleven Madison Park (then a Meyer owned restaurant) which sits next to the park, has three Michelin stars and in 2017 was #1 on the World's 50 Best Restaurant's list.
