In Sikhism, a langar is the community kitchen of a gurdwara, which serves meals to all free of charge, regardless of religion, caste, gender, economic status, or ethnicity. People sit on the floor and eat together, and the kitchen is maintained and serviced by Sikh community volunteers who are doing seva. The meals served at a langar are always lacto-vegetarian.

Sikhism, also known as Sikhi, is an Indian religion and philosophy in particular for the Sikh ethnoreligious group that originated in the Punjab region of India around the end of the 15th century CE. The Sikh scriptures are written in the Gurumukhi script particular to Sikhs.
