About Chef

Jerome "Chef" McElroy, often referred to as just Chef, is a fictional character on the Comedy Central series South Park who was voiced by Isaac Hayes. A cafeteria worker at the local elementary school in the town of South Park, Colorado, Chef is generally portrayed as more intelligent than the other adult residents of the town, and understanding to the children. His advice is often sought by the show's core group of child protagonists —Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick — as he is the only adult they completely trust. He frequently gives completely honest advice without considering whether it is appropriate for children, usually in the non sequitur form of a lascivious soul song.
