Bring the kids back to a time when texting consisted of a pen and paper and social networking was only available with face-to-face contact at Musee Mecanique at Fisherman's Wharf. This antique arcade is one of the world's largest privately owned collections of mechanically operated musical instruments and arcade games, all available for play. Don't worry about paying ‘Laughing Sal’ as you walk through his open mouth to enter the Musee —admission is free.
