"The Persian-themed Aub Zam Zam is a true San Francisco original and unlike any other bar you'll find in the city. Though there's a much lower chance of getting kicked out ever since the original owner, Bruno, passed away in 2000 (he was famous for finding any excuse — ordering wrong, being annoying — to send people on their way), not much else has changed at this local haunt that opened in 1941. Play some jazz on the jukebox, grab a seat at the horseshoe-shaped bar, and order a martini — the bartenders make some of the best in town. Just be prepared to pay in cash." - Paolo Bicchieri
