River Cottage is an all around social enterprise. They have a restaurant, two schools (one for chefs and one just for amateurs or people who have an interest in learning for a specific event), a farm and various events. The for-profit company was founded by the renowned Hugh Fearnley-Whittingstall in 2004. He's a celebrity chef, writer and TV personality that also participates in philanthropic ventures.
As a social enterprise, River Cottage considers its values to be central to the way in which they run business. Like some definitions of social business, rather than focusing solely on profit, much of the income is re-invested into continuing the mission. The site itself, Park Farm, was designed with sustainability at its core; it's a zero carbon and low energy venture.
