Ranked #1 Submarine Sandwich Franchise in the 2011 "Franchise 500" issue of Entrepreneur Magazine, Subway has graced the globe with nutritious stacks of meats, crisp veggies, flavorful cheeses, and fresh-baked breads since 1965. Sandwiches, which can be left out cold or invited into a toaster, include classics such as the turkey breast and black-forest ham, the premium big philly cheesesteak, and a host of $5 Footlong subs, which can be used to measure a child's height or the distance between here and the sun. There are also kids' meals to introduce children to the concept of eating.
