Though generally known for a streamlined menu with few frills, Shake Shack has been churning out regional variations at a quicker clip of late, using them to test potential large-scale offerings and drum up excitement for unit openings. Here’s a look at the fast casual’s recent local items (and one that’s forthcoming).
The Chick’n Shack; Brooklyn, N.Y.
Before the chain brought its first-ever chicken sandwich nationwide, the item was introduced as a regional special that sold for $6.29. Initial demand for the sandwich—which features fried chicken, pickles, lettuce and buttermilk-herb mayo—was so overwhelming that the three locations offering the item ran out of supply in just two days.
The Carpetbagger; Atlanta
Created in collaboration with Chef Ford Fry, this riff on the carpetbagger steak dish was offered at a single Shake Shack unit for one day only. With two beef patties, cheese, pickles and smoked and caramelized onions, the $8.50 burger tested patrons’ willingness to pay a little more for one of the concept’s limited-edition offerings.
