Notes: Michael Romanoff owned and operated two Romanoff's in California: one in Beverly Hills, the other in Nob Hill of San Francisco. Born Hershel Geguzin in Lithuania in 1890, Michael Romanoff was a professional imposter, who claimed to have been Prince Michael Dimitri Alexandrovich Obolensky-Romanoff, the nephew of Russian Tsar Nicholas II. Folks generally knew he wasn't the Tsar's nephew, but Prince Michael was a well-known, successful restaurateur from 1941 to 1962.

The first Romanoff's restaurant opened in 1941 at 326 North Rodeo Drive in Beverly Hills, Calif., but relocated to 240 South Rodeo Drive ten years later. Romanoff opened his Nob Hill – San Francisco venue circa 1950s.
