The best way to describe Spark Social is as a designated food truck space. Or a permanent block party. Or a community park. The 18,000sqft outdoor space in Mission Bay features a rotating line-up of more than 150 local food vendors and hosts regular events like oyster happy hours, taco Tuesdays, and s'mores sessions. As for ambience, there's a vintage double decker bus (because why not?), fire pits, Adirondack chairs, and picnic tables.
