Things that worked well for me: 1) Rock climbing gyms. I made a lot of great friends at Mission Cliffs and Berkeley Ironworks. I have no natural talent for climbing, but I love the mental and physical challenge, and I enjoy the social aspect. 2) A super-social connector. When I first moved to the Bay Area, I made a ton of new connections through the marketing woman at my startup. Simply by saying 'yes' to invitations and actually following through, I found my social network increasing. 3) Meetup.com and various activity groups. When I was in Tokyo, I found Tokyo Gaijins to be a great resource for meeting people. Like food? Take a cooking class. By the way, living on the Peninsula without a car is social suicide. Move to SF, that's where all the cool kids are. Also -- potentially controversially -- SF is the home of Asian women dating dorky white guys. If you want to meet a nice girl, do what my (Asian) friend did and move to Vancouver, B.C. He went from perpetually single to dating in a few months, and got married last year.
