Dong Xuan Market is the largest of its kind in Hanoi. This sprawling complex has several floors of fashion, apparel and souvenirs at some of the best prices in the city. Even if you’re not interested in printed T-shirts or cheap sunglasses, it is still fascinating to see the comings and goings of the local traders, and there is a wet market on the ground floor where the sights and smells of exotic produce assault the senses.
