Although he had a fairly loyal clientele, Mel's food and cooking were constantly criticized by his waitresses and customers alike—especially Henry, who always blamed it for his indigestion. However, Mel's chili con carne was popular and became a plot point of several episodes. During the first season, a newspaper food critic (played by Victor Buono) dropped dead while eating Mel's chili, but it turned out that tainted Peking Duck from a Chinese restaurant was to blame. Guest star Art Carney in one episode was to be the spokesman for retail distribution of Mel's Chili ("Chili con Carney") but backed out when he discovered Vera was a distant relative with part ownership in the venture. The popularity of Mel's Chili also led to an appearance on Dinah Shore's talk show, which led to some bickering among the waitresses because Mel could take only one person along, but everyone ended up going. Mel refused to reveal his "secret ingredient" to Dinah and her TV audience during the cooking demonstration.
