Quoted from itsokay:

pinballpete come check out the PPM! I am a volunteer/tech there during the week and there is a lot to see! Due to my recent joining of pinside, I cannot update the games shown on the pinmap, but there are only a few differences.
as cornelius said, Musée Mécanique is a must see as well. It is in total tourist trap San Francisco, but the amount of coin operated gizmos there is truly one of a kind. I think there is a Four Seasons, Indiana Jones, and TAF there for sure, there is a Hyperball as well!

Quoted from TheFamilyArcade:

Gotta downvote the Oakland after dark take. First off, PPM is in Alameda, which is a pretty mellow town, and there's a decent neighborhood bar down on the corner to grab some brews. Not to mention a legendary BBQ franchise on the same block (Everet and Jones I believe).
Pacific Pinball Museum is MAnDATORy for a pinhead. Second, I don't think I've ever been there in the daylight...and I've been there with my sister, my wife and two young kids, and with friends...no worries whatsoever AND they have parking! Lastly, there are places in Oakland that are nice too, like Jack London Square, with jazz clubs and restaurants and all the stuff you want as a tourist looking to do a bunch of shit in a limited time frame.
Rec for Free Gold Watch. I'm pretty sure that place has the most pins in the city proper. I'm wearing my SFPD - SAN Francisco Pinball Dept. hoodie as I type this!
Last, is that damn Indy STILL at Musee Mech? It was there when it was still by the Cliff House out on Pacific Beach!! That and a Sing - A - Long, which is a great EM.
