The Bitter End
This was my local when I was living in San Francisco, and I could be found there most nights I was staying in the city (which was only about a third of the time anyway). It's on Clement Street in the Richmond District, a mostly Chinese and Russian neighborhood. I got on very well with Paige the bartender, as I recall, and it was there that I acquired a taste for vodka with a Guinness chaser.
