Subway has found its healthy niche in a world of fattening food. While most fast food chains are not very health conscious, this chain boasts having the freshest ingredients. Being able to watch the branded “sandwich artists” create your sub helps you feel better about what you are about to eat since you choose your fillings (as much or as little as you want). Health aside, these sandwiches are tasty and satisfying. Add chips, a drink, and a cookie–and viola you’ve got a full blown meal on the cheap. Subway’s are so popular that they’ve been bringing customers back for 40 years.
