October 17, 2010. High Tide Cocktails, at the corner of Geary and Jones in The Tenderloin, San Francisco.
This is probably my favourite commercial sign that I saw in all of San Francisco. I walked past here several times, though I never got a chance to see it at night. I'm not even sure if it lights up anymore, but I'm picturing the lights "flowing" out of the martini glass, around the sign, and down the building. Classy.
