Greens Restaurant opened in 1979 as part of San Francisco Zen Center, which includes Green Gulch Farm and Tassajara Zen Mountain center. Located at historic Fort Mason Center, in a former cavernous machine shop, Greens overlooks the San Francisco Marina with views of the Golden Gate and Marin Headlands. Green Gulch Farm, in Marin County, less than an hour north of the city, is a residential Zen community and bountiful organic farm. Year-round it provides the restaurant with seasonal produce ranging from chard, leeks and winter squash to flowering herbs - a myriad of fresh garden edibles tended with care. In addition to Green Gulch Farm, Greens draws on an extended family of local growers and organic farmers' markets for its ingredients.
