My daughter-in-law and I took a market tour and cooking class through Hidden Hanoi. We had some scheduling difficulties, which Mrs. Van was gracious and accommodating about. The market tour was excellent and informative, giving us a way to negotiate Hanoi's markets that we were unsure about until this tour. The cooking class was excellent and well worth the money, in fact it was a great deal, we learned about all the ingredients, prepared them and ate like queens. Both days, the other people attending the class were interesting travelers. We can't recommend this place highly enough. The courtyard and cooking facilities were well organized, with lots of charm, and the information was invaluable to me.
