Even if you somehow miraculously fail to notice the imposing Gurudwara Sis Ganj building as you walk down from the main Red Fort area right into Chandni Chowk (and you just might in case you are too distracted by the many sights), the intensely overpowering fragrance of the Halwa prasad will invade your nostrils and possess you, pulling you right towards the Gurudwara, goading you to enter and pay your respects, even if it is for the greedy objective of getting a spoonful of the divine prasad. Ignore at your own peril. The Gurudwara Sis Ganj is the place of martyrdom of Guru Teg Bahadur, the ninth Sikh guru and hence is a place of great reverence for the Sikh community. It is one of the nine gurudwaras in Delhi bearing historical significance.
