Around 5pm on a cold, windy Tuesday, an eclectic mix of people stand in a long line at Civic Center’s UN Plaza in San Francisco, waiting patiently. Some have big travel backpacks, a couple have tough-looking dogs, and a few are dressed like they just came from work. Suddenly a bright orange and yellow minivan arrives at the plaza. A team of volunteers wearing orange aprons emerge and quickly set up tents, tables, and giant, metal vats of steaming food. The food smells of ginger and garlic.
