Here at Shake Shack, we pride ourselves on our Chicken Shack which is available 7 days a
week. With crispy, white-meat chicken breast or thigh 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 100% cage-free chickens,
something not everyone can say these days…
Every Sunday from 30 November to 28 December, we are offering a Free Chicken Shack with any chicken sandwich purchase with promo code: CHICKENSUNDAY. Just order on our Happy Point Singapore app to taste the true difference.
