Rent a car or take the train to San Jose to The Analog Room. Call them first to see if they have anything you want to listen to. It is my favorite place of every place in the Bay Area. The vinyl alone is worth staying an extra day for, if you can make it happen. Last time I was there they had over 10 turntables set up, from Rega to SME 30.
While you are in SFO, go to dinner at Jackson Fillmore. Also off the chart.
