Langar is the term used in Sikhism for the community kitchen in a Gurdwara where a free meal is served to all the visitors, without distinction of religion, caste, gender, economic status or ethnicity. The free meal is always vegetarian. People sit on the floor and eat together, and the kitchen is maintained and serviced by Sikh community volunteers. At the langar, all people eat a vegetarian meal as equals.

In Sikhism, the practice of the langar, or free kitchen, is believed to have been started by the first Sikh Guru, Guru Nanak. It was designed to uphold the principle of equality among all people, regardless of religion, caste, color, creed, age, gender or social status. The second Guru of Sikhism, Guru Angad Ji, is remembered in Sikh tradition for systematizing the institution of langar in all Sikh temple premises, where visitors from near and far could get a free simple meal in a communal seating.It was the third Guru, Amar Das Ji, who established langar as a prominent institution, and required people to dine together irrespective of their caste and social rank. The legacy continues and langar in Gurudwara Dashmesh Darbar is served till date 24×7. Thousands of people eat langar on daily basis. Tea is also served from early morning to evening.
