Shake Shack is a restaurant chain serving hamburgers, hot dogs, french fries, milkshakes and similar foods. There are currently seven restaurants within the chain, five in New York City. The first Shake Shack located in Madison Square Park opened in July of 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. Their website has a webcam which shows the current line in real time. In 2007 the Shack began selling wine. In 2008, a Shake Shack was opened on the Upper West Side. Citi Field, the home of the New York Mets baseball team in Queens, features a Shake Shack concession stand which opened along with the ballpark in 2009. On top of the Citi Field Shake Shack sits the model of the New York City skyline that used to sit on top of the scoreboard at Shea Stadium. In 2010, Shake Shack restaurants were opened in the Theater District and the Upper East Side. Shake Shack restaurants are scheduled to be open in Battery Park City and the Fulton Street Mall in Brooklyn in 2011.
