54 Traditions is a simply remarkable place, and a must-visit in Hanoi. They have a vast collection of items from across the depth and breadth of Vietnamese cultures and can explain it all. The collection is also beautifully displayed. You can think of it as a museum visit and just learn and enjoy. But it's also all for sale, at prices that really surprised us. We bought a couple of things, and were pleased that a week or two later, we got an email with detailed information about provenance, cultural and historical context, etc. Overall, one of the best finds in our years of travels.
