A mobile street food cart is a portable kitchen set up on the road to prepare and sell road food to passers-by. Food carts are usually found in cities worldwide selling food of every sort. One allows the seller to sit or stand indoors and serve food through a window. In the other, the seller stands alongside the mobile food cart , while all of the space in the cart is used for storage and to house the cooking machines, usually a grilling surface. The cart design is determined principally by the sort of food.
