I like the idea of the Tied House in Mountain View for all the reasons you mentioned. Its very centrally located for most Bay Areans. Plus it has its own brew pub with a fairly large room in the back. We've had a couple company team events there; if I recall it seats maybe 50-60 people??

Also for SF, a meet by Ocean Beach next to The Beach Chalet, also a brew pub, might be cool. Large parking lot by the beach, etc.

One other possibility is the new Chrissy Field Park area off of the Presidio. Large parking lots, barbeque area, scenery, and open space for other activites: frisbee, kite flying, and softball. Will need volunteers to cook burgers and bring a couple of kegs (I'll help). Pretty close to dowtown SF, where we can go rage afterwards....
