Wikipedia
Street food is ready-to-eat food or drink sold by a hawker, or vendor, in a street or other public place, such as at a market or fair. It is often sold from a portable food booth, food cart, or food truck and meant for immediate consumption. Some street foods are regional, but many have spread beyond their region of origin. Most street foods are classed as both finger food and fast food, and are cheaper on average than restaurant meals. According to a 2007 study from the Food and Agriculture Organization, 2.5 billion people eat street food every day.
Today, people may purchase street food for a number of reasons, such as to get flavorful food for a reasonable price in a sociable setting, to experience ethnic cuisines, or for nostalgia.
