The Classic Buttery Jack also includes a 1/4-lb. beef patty, provolone cheese, creamy tomato sauce, green leaf lettuce, tomato, and a new "signature" bun.
The Bacon & Swiss Buttery Jack goes for a more meat-and-cheese profile and consists of a quarter-pound beef patty, hickory-smoked bacon, Swiss cheese, and creamy bacon mayo on a new "signature" bun.
You might remember the Buttery Jack was spotted in test by one of your fellow Brand Eaters last summer.
