The SF Underground Market was conceived of by Iso Rabins in early December 2009. Frustrated by his inability to get a booth at legit farmers markets (to be in most farmers markets in SF you need to be certified as the primary producer of the food you sell, and since wild foraged food grows on its own, there is technically no producer), as well as amazed by the wealth of delicious professional quality food being made in Bay Area home kitchens. The first market was held in a private home in the Mission neighborhood of San Francisco, with 8 vendors, and about 200 attendees. Now at number three (at the time of this post) , It has grown to 47 vendors and over 1,200 people attending. The SF Underground Market is an incubator. A place where budding businesses can get a leg up on their road to legitimacy.
