According to an article in the San Joaquin Historian, the original On Lock Sam was located at 125 East Washington Street between Hunter and El Dorado. It was started by an unknown person in 1898. Wong Sai Chun ad two partners bought the existing business in 1920. The restaurant became an important center of Cantonese Chinese community life in Stockton and was known for hosting important cultural and family banquets.
