• The sandwich is decent, but the chicken itself leaves something to be desired.

Shake Shack is testing a new grilled chicken sandwich at its locations in Brooklyn, New York.

The "Griddled Chick'n Club" is a decidedly healthy item for a chain that serves cheese fries, hot dogs, and double cheeseburgers. Of course, this isn't the first chicken item on their menu - that honor goes to the deliciously crispy and near-perfect Chick'n Shack fried-chicken sandwich.

The sandwich will be rolled out nationally, excluding airport and stadium locations, for a limited time starting January 26. But is it as good as the rest of the chain's chicken? We grabbed one to find out.
