The Old Quarter, near the scenic Hoan Kiem lake, has the original street layout and architecture of the old Hanoi. At the beginning of 20th century, the city consisted of only about 36 streets, most of which are now part of the old quarter. Each street then comprised of merchant and household specialized in a particular trade, such as silk traders, jewellery, etc. The street names nowadays still reflect these specializations, although few of them remain exclusively in their original commerce. The area is in general famous for its small artisans and merchants, including many silk shops. Local cuisine specialties as well as several clubs and bars can be found here also. A night market in the heart of the district opens for business every Friday, Saturday, and Sunday evening with a variety of clothing, souvenirs, and food. Wikipedia
