Shake Shack – free burger pass!

Calling all Shake Shack “Shaddicts”. To help promote the new Delta Terminal 4 outpost of Shake Shack, the company is offering a free “burger pass” for a complimentary Shack Burger. Stop by their pop-up shop where visitors can pick up a boarding-pass-like voucher that entitles the bearer to one free ShackBurger at any participating Shake Shack, and not just the new one in the airport.

Date: May 19th through May 22nd

Time: 11a – 3p

Location: the Delta T4X faux airline terminal @ 376 West Broadway (at Broome Street)
