Shake Shack rolls out chicken sandwich nationwide

Shake Shack announced Thursday it's expanding the release of a popular fried chicken sandwich to its menu nationwide.

The Chick’n Shack debuts after the restaurant tested the sandwich this summer at its Brooklyn, N.Y. locations.

The sandwich features a crispy all-natural and antibiotic-free chicken breast with lettuce, pickles and a zesty buttermilk herb mayo.  It has won kudos for its flavorful, juicy chicken and the sandwich become one of the top five best selling food items.

We got a taste and know why.

The release of the sandwich has been closely watched since reports surfaced last spring that Shake Shack filed a trademark application for "Chicken Shack."  Danny Meyer’s burger chain is already a favorite among foodies for its attention to quality ingredients.

The $6.29 Chick'n Shack will be available at all domestic locations.
