They themselves do all the necessary work such as cooking and cleaning. These children are selected (挑选) in Amsterdam. After training (培训), they may work in the Restaurant for four weeks. All of them like their work. This restaurant was founded (创办) in 1983 by a woman cook, who wanted to give the children chances to learn to be useful to the public.
