Customized food carts are a great way to get started in the street-food industry! Because they are compact enough to be pulled by a car you already own, or even pushed by hand, they are far less expensive than purpose-built food trucks. Food cart trailers can be large or small, and they have the advantage of allowing cooking. They also give you a surprising amount of room for invention. They provide many more options than a food cart, and are far less expensive than a truck. Consider, for example, the possibilities of a repurposed Airstream trailer, shining sleek and silver, wafting good smells from the full kitchen stashed inside its retro exterior.
