Operating your own food concession stand, tent or trailer can be a rewarding business experience. Sell traditional foods such as hamburgers, hotdogs and fries or come up with a unique food idea that nobody else is selling at concerts, shows or events. The website covers concession food topics such as food trucks, concession stand signs, food booths and alternative ways your charity or group can make some money. Concession trailers are big business and can be highly profitable at the right location, selling the right food and drinks. Photos and resources also provide you with food for thought if you are planning to become a food vendor.
