Panera landed the honor of favorite sandwich chain in America, according to a consumer survey conducted in August by Market Force Information. The survey polled more than 7,600 people and looked at 14 sandwich/wrap chains. A voting system was used, which accounted for chain size and customer visits, to narrow down the top picks to Panera, Jason’s Deli, McAlister’s Deli, Firehouse Subs, Quiznos, Jimmy Johns and Subway.
