Here at Shake Shack, we pride ourselves on our Chicken Shack which is available 7 days a week. With crispy, white-meat chicken breast over lettuce, pickles, and buttermilk herb mayo on a toasted potato bun, this sandwich outshines its competition. And what makes our Chicken Shack even better, is that it’s made with antibiotic-free chicken, something not everyone can say these days...

Every Sunday in April, we are offering a Free Chicken Shack with $10 minimum purchase with promo code: CHICKENSUNDAY. Just go to your nearest participating Shake Shack or order on our app or website to taste the true difference.
