Spring through fall, some 30 food trucks and pop-up cubes circle their wagons at SF's largest mobile-gourmet hootenannies on Friday night at Fort Mason Center, and 11am to 4pm Sunday for Picnic at the Presidio on the Main Post lawn. Arrive early for the best selection and to minimize waits.
These weekly parties are a great way to appreciate the breadth of the SF food scene while rubbing elbows with locals. Standouts in 2019 include Lobsterdamus, an LA operation offering a signature garlic noodles and lobster dish, and the mouthwatering meats of Horn BBQ, which are smoked on-site. Beer, wine and cocktails warm you up for dancing to live music and DJs.
There are more Off the Grid events in various other neighborhoods on different days, but they're smaller affairs; these two are the ones to seek out.
