Binh Tay Market, constructed by the French in the 1880s, is located in the centre of Vietnam’s largest Chinatown district. Unlike Ben Thanh Market in District 1, this market mainly serves the local population with its extensive range of fresh fruits, vegetables, poultry, meat and seafood from regions across Vietnam.
Also known as Cholon Chinatown Market, Binh Tay Market occupies a two-storey building along Thap Moui Street. Travellers can also find an assortment of handicrafts, lacquerware, and textiles that are sold in bulk, though goods are not varied compared to other (more touristy) markets in downtown Hanoi. Along with the interesting historical and cultural aspect of Cholon, Binh Tay Market is great for experiencing the local lifestyle and sampling unique Vietnamese-Chinese delicacies.
