About 500 kg of dal, 600 kg of vegetables and one tonne of rice is what it takes to feed thousands of people at the Sis Ganj Gurdwara in Chandni Chowk on an average day. The langar or community kitchen at the popular gurdwara has always been busy, with everyone from local shopkeepers and foreign tourists to the faithful and the destitute sitting down for a meal. But for the past two weeks, the lunch rush at the langar hall has been more hectic than usual, and officials of the gurdwara management say extra food is being cooked.
