Hoping to improve business at Mario's Pizza Parlor, Samantha mounts an advertising campaign to publicize the failing establishment. At the same time, Darrin is hired to build up an ad campaign for Mario's main competition, a national pizza chain owned by the powerful Linton Baldwin (Alan Hewitt). It is inevitable that Sam ends up saving both Darrin's job and Mario's restaurant. Mario is played by Vito Scotti. Written by Richard Baer, "Eat at Mario's" originally aired on May 27, 1965. ~ Hal Erickson, Rovi
