There is also a nicely located store on in Burlingame, about halfway up Burlingame Ave, next to Peets Coffee. You can take Cal-train and it stops at the Avenue. Like P.A., it is a nice street to hang for a couple hours and Cal-train is easier walking than P.A.
Also a new store in Stonestown Mall, off 19th Street in S.F. probably need a car, however.
Of course nothing beats the S.F. flagship for the WOW factor...take Cal-train to the Millbrae station, switch over to bart, take bart...to the powell station, I believe it is.
