Speaking of fractional addresses, the original address of the Hidden Vine wine bar was ½ Cosmo Place* in the alley behind Le Colonial. IIRC, the front was a single doorway leading steeply down to a converted hotel basement containing a very nice wine bar. http://www.vinography.com/archives/2007/06/san_francisco_wine_bar_the_hid.html http://www.vinography.com/archives/2007/06/san_francisco_win... (620 Post Street is the Fitz Hotel on the other side/above it.) It looks like another business is/was there (Barrel Room Wine Bar) and the street number must have changed (2 instead of ½). https://www.google.com/maps/@37.7881276,-122.4120619,3a,15y,225.17h,83.07t/data=!3m6!1e1!3m4!1sJK_9h4XTXuzLHHNdAbUZ5A!2e0!7i16384!8i8192 https://www.google.com/maps/@37.7881276,-122.4120619,3a,15y,... EDIT: * I just learned that ½ alone is, according to the USPS, an invalid street number. They still used it anyhow. https://pe.usps.com/text/pub28/28ape_004.htm https://pe.usps.com/text/pub28/28ape_004.htm
