Hungry commuters now have New York burger favorite Shake Shack as an option in Grand Central Terminal. On weekdays the location serves Shake Shack’s popular egg and cheese breakfast sandwiches, previously available only at JFK airport, fro m 7-10:30 a.m. Even better, the location also serves a special blend of Stumptown Coffee to perk up your commute. Other Shake Shack staples, including hand-cut fries, shakes, and frozen custards, are also available throughout the day. Like any Shake Shack, this location is always packed, but is well worth the wait.
