Sam Wo is a Chinese restaurant located in San Francisco, California. The restaurant's first location on 813 Washington Street was famous for being a venerable mainstay in the local Chinatown area, having been in the same location since 1912. Sam Wo gained notoriety in the 1980s for being the employer of Edsel Ford Fung, who was known locally as the "world's rudest waiter". The restaurant was closed in 2012 due to safety concerns, and reopened in 2015 on nearby Clay Street.
