Shake Shack is one of the best burger restaurants that has come a long way from the legendary Madison Square Park hot dog cart. The company's 12,000 square-foot headquarters in NYC has plenty of space for employees with an industrial design scheme that imbues mid-century modern furniture into the mix that is spreading over three-story. Alongside the offices and conference rooms, there are also libraries matched out with wood flooring and a test kitchen. Moreover, no matter what mood the employees are in, the calm atmosphere throughout the open-concept workspace, they can genuinely develop new menu items that eventually benefit our tastes and stomachs.
