If you're just asking in general, Kezar Pub, Mad Dog in the Fog, hell considering there's no college ball that night I'm sure any old sports bar would show it, but go to the soccer friendly ones first. Just Google any of those two names for info. As for an organized viewing, none that I know of in The City.
It's a weeknight so it's a longshot I'll get to Kezar... I'm plotting to head to the Prince of Wales Pub in San Mateo--a bunch of us were there for the last game and given that people will be off work by that time, be convenient to head there. Any ideas, let us know...
San Mateo is a bit far from SF... I will try to make it to Kezar if I can bail on work at 4:30. Go Quakes!
If you are nowhere near a computer and need info you can get addresses, phone numbers, ect via text message on a cellphone from Google SMS.
If I can't get out early, I'll try the Royal Exchange in the financial district. I have caught some EPL games at lunch time there in the past. 301 Sacramento St San Francisco, CA 94111 Mon-Fri: 11am to 11pm Tel: (415) 956-1710 http://www.royalexchange.com/
If you work downtown, Steffs on 2nd St between Mission and Howard shows a lot of soccer. It's just a neighborhood type bar, no real amenities, but you can get there in time to watch the game.
