The Creme Brulee Cart is one of many licensed and unlicensed food vendors who have recently hit the streets of San Francisco, especially in the Mission District. The area’s bars, streets and parks host a caravan of food sellers who connect to their customers via social networking Web sites like Facebook and Twitter.
But the trend, which is playing out across the country, goes beyond individual efforts. The nonprofit La Cocina will host its first San Francisco Street Festival in August, followed by a similar Eat Real Festival in Oakland from the organizers of Slow Food Nation. A new street food-focused market will debut at the Ferry Building on Thursdays in July.
