We are running it back! Free Chicken Shacks on Sunday this football season! 

Starting on Sunday, September 8th we are offering a Free Chicken Shack with $10 minimum purchase throughout this football season. Just like professional football players, we too work on Sundays and couldn’t be happier to serve up antibiotic-free Chicken Shacks on Sunday Game Days. There is no better combination than watching your favorite team on Sundays with a sandwich that’s made-to-order and only uses the highest quality ingredients. 

Want to have the best Sunday ever? Just use promo code CHICKENSUNDAY and it can be yours. 

To make sure you remember why it’s the best, it’s because our sandwich is made with crispy, white-meat antibiotic- free chicken breast over lettuce, pickles, and buttermilk herb mayo on a toasted potato bun, this sandwich outshines its competition.
