For an occasionally harrowing (but always interesting) peek into traditional Hanoi, spend an afternoon navigating the maze of the Old Quarter markets. Traditionally, certain streets were named after the product that was sold there (i.e. shoes, textiles, gold, etc.). Much of that tradition remains, and there seems to be very little you can't find here - from party products to jewelry to delicious street food. Keep your head up -- not just for the sights but also to be aware of the traffic whizzing by in all directions.
