Chef Danny Meyer is expanding his burger empire. Shake Shack will open an Atlanta location by summer 2014, at the new luxury development Buckhead Atlanta. The New York City burger and shake concept started in Madison Square Park in 2004, and has since garnered a cult following for items such the roadside burger, flat-top hot dogs, french fries, frozen custard, and more. This will be Shake Shack’s first Georgia location.
