If you come to SF, you must stop by the George Lucas digital art center in the Presidio (old military base)! The grounds are gorgeous. And there's a Yoda fountain! There's a breathtaking view of the Palace of Fine Arts. Seriously, the grounds are beautifully manicured and it's just so aesthetically pleasing. If you're not into the cheesy touristy areas and want to find a hidden gem go here.
