Firehouse Restaurant Group operates and franchises more than 250 Firehouse Subs sandwich shops in a dozen southern states. The chain offers a variety of hot and cold sub-style sandwiches, as well as soups, salads, and sides. Brothers and fire fighters Robin and Chris Sorensen started Firehouse Subs in 1994 after gaining popularity as firehouse cooks. Although most of its units are located in the Southeast, in 2009 Firehouse Subs has taken advantage of commercial real estate bargains and expanded into new regions, including Indianapolis, Denver, Phoenix, and Las Vegas.
Brothers Chris and Robin Sorensen, both former firefighters, opened their first Firehouse Subs restaurant in Jacksonville, Florida, in 1994, and began franchising the concept just a year later. Each Firehouse Subs franchise is decorated with firefighting memorabilia and artwork, with a menu that features hot and cold subs and salads.
