I thought most of the article was pretty spot on, except for the PBR being the drink of SF.
PBR is all over hipster bars in the Mission, but there are plenty of places where you can't get it (most bars in the rest of the city). The true drink of SF in my opinion is Fernet, which is heavily consumed by long time San Franciscans. Fernet has a long history in the Bay Area (SF is even listed in the Wikipedia page on Fernet http://en.wikipedia.org/wiki/Fernet), and surprisingly it is stocked in almost every bar. I've personally had it in everywhere from the Kabuki movie theatre to bars in North Beach to the Mission.

TLDR: Fernet is the drink of SF.
