Last stop — a Double Shack Burger with fries!

The wildly popular burger joint Shake Shack is eyeing a spot in the dining concourse at Grand Central Terminal, a restaurant spokeswoman said last night.

The chain — which launched with a stand in Madison Square Park and has since expanded to locations including Citi Field, Midtown and Battery Park City — will soon share its plan with the MTA.

“We are looking to make our home in vibrant locations throughout New York City and beyond,” the spokeswoman said.
