Agostino "Bimbo" Giuntoli (September 22, 1903 – July 25, 1992) was an Italian-born American nightclub owner and entrepreneur.

Giuntoli was born and raised in Chiesina Uzzanese, Pistoia, Tuscany, Italy. In 1922, aged 19, he emigrated to San Francisco, arriving with just $2.^[1] He worked as a janitor at the Palace Hotel and then as a cook nearby, where Monk Young, his boss, was unable to pronounce his name, and called him bimbo instead (Italian for "boy"), and the nickname stuck.^[2][3]

In 1931, the 365 Club, 365 Market Street, was opened as a speakeasy and after-hours gambling club, owned by Young and managed by Giuntoli. It soon became the most popular illicit drinking establishment in town. Musical artists and dancers showcased their work, including a young Rita Hayworth dancing in the chorus line. An optical illusion achieved by mirrors made the large fish tank above the bar appear to have a nude woman swimming in it. Bar patrons marveled at Dolfina, "the Girl in the Fishbowl".^[3]

In 1936, he employed Victor Rosellini, his wife's younger brother, in front of house. Rosellini went on to run several restaurants in Seattle, and later became president of the National Restaurant Association.^[4]

In 1943, Giuntoli became a naturalized US citizen. In 1950 or 1951, Giuntoli, by that time sole owner of the 365 Club, purchased 1025 Columbus Avenue and moved his club there.^[2]

As of 2014, the club is still there, owned and run by his grandson, Michael Cerchiai, who celebrated his eight birthday there with a Batman-themed cake, while Smokey Robinson played live.^[5][6]

In 1928, Giuntoli married Emilia Rosellini (December 26, 1908, Tacoma, WA – November 2, 1989, San Francisco), and they had two daughters:

• Diana Isola Cerchiai (born March 18, 1929, San Jose). She has 5 children.
• Yvonne Fine Sangiacomo (born February 11, 1932, San Francisco). Her husband, Angelo Sangiacomo, is a real estate developer, and together they own about 50 apartment buildings in San Francisco.^[7] Their seven children all attended L'Ecole Notre Dame des Victoires in San Francisco.^[8]

Giuntoli died in San Francisco on July 25, 1992. He was survived by his two daughters, 12 grandchildren and 10 great-grandchildren.^[1]
