Her in Hanoi you can find food markets all around town despite the growth of supermarkets. It seems that most shopping is still conducted at local wet markets.
Most markets are very well accessible they are open from early morning until evening, every day, and are selling all the fresh food you’d expect. It’s a place to go if you want fresh fruit –prices are usually lower but you have to negotiate a lot.
The experience you will have is incredible. The smells, the wet floor from rain or fish buckets, most shoppers come on motorbikes and are squeezing through narrow aisles. That’s a real Vietnamese market and an experience you don’t want to miss. The best times are early mornings or late afternoons. At these times you will meet most locals and will get the feeling of this colorful environment.
