One of San Francisco’s greatest hidden treasures can be found at the Letterman Digital Arts Center in the Presidio. At the entrance to is a fountain topped by a statue of Yoda. But that’s not all. If you pass the fountain and enter the doors to LucasFilms you will find original Star Wars merchandise including life-size Darth Vader and Boba Fett (as well as light sabers, MTV Movie Awards, Clios and more). Well worth the visit.
