is your local game store. Good place. Has play space and events.
Also my buddy James runs the Walnut Creek Board Games Meetup
which is about 5 miles from there.
Further out from there, about 20 miles each, is EndGame
in Oakland and our game group
which meets in Berkeley on Tuesdays and Thursdays.
There are even more further afield, but I'll let someone else post about those. Basically, you'll have no shortage of opportunities.
