Food trucks and live music every Friday from 5-10 PM (it ends at 9PM starting in Nov). Half priced admission to the museum with kids 18 and under entering for free!
Great place to go for grub on a Fri night. Senor Sisig is worth the long wait. The Chairman's steamed pork belly sandwiches are awesome. Rich meat, tender roll, acid from daikon pickles cuts the fat.
These food trucks offer some of the best street food in San Francisco. They notify people of their location via Twitter and are primarily powered by solar panels.
Koja kitchen was THE BOMB! An the Go (garlic noodles, lemongrass skewers) was DELICIOUS! Cremé brûlée cart was very disappointing. Pacific Puffs (creme puffs) was HEAVENLY. Not even crowded either!
If Cupkates truck is here, or anywhere in your vicinity, you should RUN to her!! The best cupcake I've ever had, and I'm an admitted cupcake whore. : )
