Forager and founder Iso Rabins created San Francisco's hugely popular underground market in 2009 to give fledgling entrepreneurs a place to sell to the public without jumping through regulatory hoops. Two years later, it hosts more than 35 of the Bay Area's finest home chefs. A simple online registration is required for attendees of the monthly event to maintain its "underground" status. Once inside, people gather around rows of cart tables for bacon-caramel popcorn and orange marmalade sandwiches.
