Gwinnett Chick-fil-A giving away free sandwiches for National Sandwich Day

Some of 1600 chicken sandwiches made to be given away in a promotion, at Chick-fil-A?s first location in New York, Sept. 23, 2015. Privately-held Chick-fil-A expects to post double-digit growth this year, but the chain remains unfamiliar to most in New York -- one of the toughest and unforgiving restaurant markets in the country.
