In an effort to encourage more people to get vaccinated against COVID-19, Shake Shake is expanding its free fries vaccination offer to all locations in the U.S.
From May 21 through June 12, 2021, participating Shake Shack restaurants will be offering free Crinkle Cut Fries with the purchase of any burger or chicken sandwich – including the new Avocado Bacon Burger + Chicken – by simply showing proof of vaccination in-store.
Just take note that the offer excludes Shacks located in airports, stadiums, and ballparks.
The free fries promotion for vaccinated customers kicked off in New York last week and is part of the brand’s ongoing commitment to support local communities in which it operates.
