Chandni Chowk, originally meaning moonlit square or market, is one of the oldest and busiest markets in Old Delhi, now in central north Delhi. Built in 17th century by Shah Jahan and designed by his daughter Jahan Ara, the market was once divided by canals to reflect moonlight, now closed, yet it still remains one of Asia's largest whole sale markets.

Chandni Chowk's specialty is the variety of its markets and their Indian-ness. From authentic Indian food, delicacies and sweets of more than 1,000 kinds, to sarees with chikan and zari work. There are lots of narrow lanes with many shops selling books, clothing, shoes and leather goods, electronic and consumer goods and whatnot. The area, even more so than the rest of the city, is very congested. This is also a good place for window shopping.
