Famous Delhi 6 (Old Delhi) market, Chandni Chowk is the busiest market in the city. It's got narrow lanes, cramped streets, and all things wholesale. You'll also find some of the best street food here—especially if you're a fan of kebabs. It open around 11am and shuts down at 8pm closed on Sundays. We would, however, suggest getting out of here before the sun sets.
