Grace Kitchens started a couple of years ago due to the increase of people not having food and water in the UK. Currently they are serving food in Central London, and in Kingston, and is looking to go national.
UPDATE: There are now Grace Kitchens centres dotting around Europe.
Each week several people will get together, each bringing vegetarian food \ water \ fruit \ salad \ tea \ coffee etc and then serve. They are not promoting any religion, their agenda is just to spread love through service.
