Food Trailers or carts are less expensive than food trucks, usually pulled by a vehicle or pushed by hand. They’re fairly easy to maintain and, in many areas, require less licensing than the full-sized food trucks.
Concession trailers have been around for decades and is a multibillion-dollar industry. often found at fairs, sporting events, or other places where they can be unhitched and sit for awhile. Unlike carts, trailers allow for cooking and have room for two or three people inside.
Cart owners however prepare food in advance or purchase ready-made food like ice cream bars. Then, the food is heated up or pulled from the freezer. Food carts used to focus on simple fare like ice cream and hot dogs, but have expanded their menus in recent years to include dishes like kebobs, gyros, salads, and fish and chips.
