Not many tourists in Oct/Nov which was ideal. Most just groups catching boats up river to Can Tho. We found the big local market near the cross river bridge, one of the best we've seen.
Be careful of touts near the riverfront and men selling Mekong boat tours that they fully honor. Cross the main bridge to see bulk food handling across the river. Best restaurant with no tourists is Chi Thanh. Menu in English as well.
Once the market and pagodas visited, there is not much to see. Or you want to visit the small island around with honey farm, paddling in the Mekong and other stuff in that range.
When you come to the city, you will feel a sense of relaxing (comparing to HCM city). You don't feel the rush and busy life that you can feel in a big city.
The people are friendly. If you can get someone from the area to take you to some interesting places, that would be great. Remember to choose the hotel carefully.
The tour to the islands is worth doing. Inexpensive for a group with small donations and tips as you move around the island.
The tour is essentially a look at the lives of the inhabitants; their work such as candy making, bee farming (good deals on pure royal jelly) riding the canals on boats, traditional music and song... and have lunch at a beautiful resturant with great food.
