Besides what people have already suggested, you can take Caltrain to downtown Mountain View and take a taxi to the party. (Usually there are taxis on the station) It's a 7 minute ride, so you'd probably pay around 7-12 bucks. The train ride from SF to MV is 50ish minutes on the weekends, so bring something to do on the train ;-)
