NYMag reports that Danny Meyer's Shake Shack, the Madison Square Park kiosk, will make its unofficial debut next weekend during the Big Apple Barbecue Block Party, and officially July 1. The shack will serve burgers, crinkle-cut fries, the Chicago-style hot dogs that had people waiting in very long lines last summer, PLUS frozen custard! Ted Drewes of St. Louis, famous for their frozen custard -- "a rich, smooth frozen custard with cream and egg yolks. It's a wonderful product not to be confused with soft-serve ice cream, which contains chemicals," is the inspiration and "benchmark" for the Shake Shack's version. Go ahead and prepare yourself for some insanely long lines.
