Hoi An is very famous for 2 things: great tailoring and great food.
Foodie Tour
As many of the best places to eat in Vietnam are, so is the Ba Le Well restaurant, tucked down a lane.
Every weekend from around 7pm every the streets running north from Hang Dao are closed to traffic (almost) and vendors set up stalls selling all kinds of things and food at the Hanoi Weekend Night Market. The Old Quarter functions as a very charming backdrop for all the little stalls. It is mainly a place to go for the busy atmosphere, souvenirs, things made of polyester or nylon and fake luxury-brand stuff. If hungry, go for the kebab spears and fresh lemon or passionfruit juices.
(Almost) All great cities has one and Singapore is no exeption: Chinatown!
