This summer, Shake Shack has been testing a fried chicken sandwich at its three Brooklyn locations. Like with its primary innovation -- better ingredients and preparation methods -- Shake Shack is aiming toward food habits of the future. While burger sales still eclipse chicken sales at fast food restaurants, according to research firm NPD Group ($7.9 billion vs. $5.4 billion in the year ending March 2015), chicken is growing at a faster clip, up 3% in the same period, versus 1% for burgers. Established chicken chain Chick-Fil-A says that it invented the fried chicken sandwich in the 1960s. So, we at TheStreet decided to see how the two chicken sandwiches stacked up. We went to a Shake Shack location in the hip Dumbo neighborhood in Brooklyn to pick up a dozen ChickenShack sandwiches. We also scooped up a sack of sandwiches from Chick-Fil-A. Six lucky sandwich testers were selected among staffers at TheStreet and we used the highly scientific 'plate method' to determine a winner. Watch the video to see who won the taste test.
