Celebrating their 100th location opening in Boston Seaport, Shake Shack is giving away 100 burgers at each location. The first 100 guests at Shake Shacks worldwide (with the exception of stadiums and ballparks) will receive a free single ShackBurger (or a burger of equal or lesser value).
How to get free burger:
- Visit a Shake Shack near you you starting at 10:30AM on Tuesday, August 16. The giveaway ends at 12PM.
* While supplies last. The lines are obscenely long to begin with at Shake Shakes, get ready to a long wait that might not end in a free burger.
