We had a private tour with Ha, who was knowledgeable and enthusiastic. His plan was to let us sample about 10 foods, but we stopped after 3 very tasty main courses as the tour was done over lunch. Thereafter, we had a delicious tropical fruit salad followed by green tea. It was simply delightful. For the rest of the time, Ha took us around the Old Quarter, sharing his knowledge and experience of living in Hanoi.
