Shake Shack, located in Madison Square Park, opened in July 2004. The restaurant was conceived and developed by Danny Meyer's Union Square Hospitality Group, which maintains restaurants in the Union Square area. The building in Madison Square Park was designed by Sculpture in the Environment, an architectural and environmental design firm based in Lower Manhattan.
Shake Shack was named "Best Burger 2005" by New York magazine. During the summer, the wait in line for service can stretch to over an hour, especially on weekends when the weather is pleasant. A webcam on the restaurant's web page shows the current line in real time.
