Fifteen
Fifteen is one of the country's most famous social enterprises, thanks to Channel 4's hit TV show 'Jamie's Kitchen' which was broadcast in 2002. The programme followed celebrity chef Jamie Oliver as he set up a restaurant which would double as a training programme for disadvantaged young people interested in becoming chefs.
Many of the 16 to 24-year-olds accepted by the Fifteen Foundation have criminal backgrounds or have suffered from addictions or homelessness, but those who prove themselves passionate about food, as well as being committed and hard-working enough, are given a year-long work placement at the restaurant.
Fifteen has proved to be a massive success and five years on is one of the capital's most popular restaurants. Every year new trainees start the course - which includes college learning and work experience as well as trips to farms, vineyards and fisheries.
Those who graduate are sent off around the world on work placements or to open their own restaurants often passing on the opportunities granted to them by hiring disadvantaged youths as staff.
The restaurant has spin-offs in Amsterdam, Cornwall and Melbourne and the brand looks set to keep on growing.
