A free kitchen is attached to every Gurdwara. There, the food ("Langar") is prepared and served. Other people and communities are allowed to visit a Gurdwara. This is one of the things that the Sikh community does to improve relations and understanding between Sikhs and other communities. These visits help satisfy others' curiosity about Sikhism. They also help visitors to better understand the Sikh religion, customs, and culture.
