From Wikipedia: The play is set in Nick's Pacific Street Saloon, Restaurant and Entertainment Palace, a run down dive bar in San Francisco. Much of the action of the play centers around Joe, a young loafer with money who encourages each of the bar's patrons in their eccentricities. Joe helps out a would-be dancer, Harry, and sets up his flunky, Tom, with a prostitute, Kitty Duval. The bar is frequented by a number of colorful characters, including a frenetic young man in love, an old man who looks like Kit Carson, and an affluent society couple.
