It’s hard to imagine a place of worship more welcoming than Gurudwara Sis Ganj Sahib in Chandni Chowk. From the moment you step through the gates of this Old Delhi landmark, its Sikh members embrace you—ushering you to the shoe drop, helping you tie a scarf around your head, and explaining the ceremonial rituals taking place around you. The ragas performed on harmoniums and tablas are hauntingly beautiful, drawing you deep inside with their modal drones. Every guest, regardless of race, class, gender, or religious belief, can join the langar in the evening, where free vegetarian meals are prepared and served daily by volunteers. Like shining the shoes of strangers while they worship, working the communal meal is a selfless act of service, or seva, and speaks volumes about Sikhism’s devotion to peace, love, and equality. A must-do in Delhi.
