Shake Shack is an American fast casual restaurant chain based in New York City. It started out as a hot dog cart inside Madison Square Park in 2001, and its popularity steadily grew. In 2004, it moved to a stand within the park, expanding its menu from New York–style hotdogs to one with hamburgers, hotdogs, fries and its namesake milkshakes.Since its founding, it has been one of the fastest-growing food chains, eventually becoming a public company filing for an initial public offering of stock in late 2014. Our scope in Shake Shack was the full development of the interior designs and FF&E in addition of the MEP works .
