Bacon Cheddar Fry, oh my! Stop by the Shack to taste Bacon CheddarShack’s new friend, Bacon Cheddar Fries, available Friday, August 5, 2016 for a limited time at all U.S. Shacks (‘cept for JFK Airport Shacks, which will start serving up the Bacon CheddarShack shortly thereafter). Like the Bacon CheddarShack burger, Bacon Cheddar Fries ($4.69) are topped with smoked Niman Ranch bacon and Wisconsin aged cheddar cheese sauce. Bring home the bacon!
