Abstract: My invention, the “Portable Self-Contained Mobile Vending Unit,” revolutionizes the single chafing dish equipment used by caterers as well as the small steam table used by food vendors in a mobile vending “hot cart.” Caterers as well as mobile food vendors can offer their customers a complete professional looking buffet style set-up of foods, indoor or outdoor, with a minimal amount of set-up. Another benefit is that the equipment is lightweight as well as durable, and requires no maintenance. The expansion of the standard style mobile vending “hot cart” from one or two full chafing dish compartments to as many as seven additional full size portable steam pans, offers a food operator endless potential. Additionally, the self-contained style saves the food caterer from setting up a separate table to accommodate his separate chafing dishes.
