When the bakery was first built, it was known as the San DiegoSteam CrackerFactory, and made crackers for use on ships travelling from the Port of San Diego. In 1899 the building was sold to J. Millender, who leased it to a series of bakers whilst using the upperstoreys of the building as residential or hotel rooms. The building was sold again in 1920 to Alois Kuhnel and Francis Smith, who ran the Royal Pie Bakery. When Alois Kuhnel died the bakery was taken over by his son, Alex Kuhnel, who ran the bakery as a trade supplier. The bakery closed in 1998 when Alex Kuhnel died, and the building now hosts an Irish pub and restaurant.
