You should keep an eye on the events calendars - and not just tech meetups. Get outside of the tech bubble.
Here are some things I've enjoyed:
Live Jazz at Club Deluxe, Madrone Art Bar, Revolution Cafe, Amnesia, Mr. Tipples, SFJAZZ
First Fridays in Oakland - check out some local art
Get a museum membership and visit all of the museums, attend events, or check out some street art.
Extension courses at Berkeley Extension or City College of San Francisco, GIS Education Center, etc. Take something random like a foreign language or art class.
Free city walking tours to learn about the history of different SF neighborhoods:
Wander around to different views of the city like Corona Heights, Tank Hill, Buena Vista Park, tiled steps, etc. There are some meetups that do this kinda stuff together also.
Rent a bike and ride through Golden Gate Park to Cliff House.
Return of the Cypher live freestyles and often breakdancing at the Boom Boom Room.
Volunteer your time and skill for educational orgs like ScriptEd or TEALS or social/political purposes like GeoCorps SkillShare or Code For America.
Eat at places besides your company. The Bay Area has so many different cuisines from around the world.
Go to one of the Nerd Nite / science events at a place like Rickshaw Stop or meet some other types of people at bar trivia.
Join an intramural league or go to a board game night.
