On Hollywood’s biggest night, many A-listers are known to stop by their fave fast food spot to fuel up. As such on Sunday, March 10, Shake Shack is announcing a nationwide deal for guests who love stars just as much as they love their burgers and fries. 

The fast casual chain has guessed how long Sunday night’s Oscars award show will last, since it has had a history of unpredictability. If the show goes over or under 3 hours and 31 minutes, consumers will receive a free Chicken Shack sandwich or SmokeShack burger.

Here’s how it works: Starting this Monday, March 11, through next Monday, March 18, any guest who places a $10 order at a Shake Shack kiosk, on shakeshack.com or the Shack App can score a free sandwich or burger using the code BIGWINS at checkout. 

If the awards show goes over 3 hours and 31 minutes, the Chicken Shack will be free, but if the show is under 3 hours and 31 minutes, the SmokeShack will be free.

Fans in Los Angeles can even join the stars at the West Hollywood Shake Shack location, which will be getting a full glam makeover inclusive of a red carpet, big bright lights, and many surprise moments. 

To celebrate the nominated stars, Shake Shack is offering free ShackBurgers to nominees credited in all categories available at the West Hollywood Shack on Sunday with proof of ID.
