When I moved back to the Bay Area after having lived in the south of France for years, one of the first things I did was set up a sort of "salon" of people I found interesting in the space I liked -- and it worked like a charm. We met once a month for the entire time I was there, with eventually the coolest collection of people. All it took was setting the calendar date, inviting people, and prompting good questions to discuss. Recommended.
