Saigon is one of the world’s great foodie cities and therefore it is almost impossible to go hungry even at the most unlikely time of night.
You won’t find really gourmet fare at the witching hour but it is easy to find a steaming cauldron filled with soup or stew, a sandwich seller packing baguettes with cold cuts and salad or a container bursting with steamed buns stuffed with pork, egg, Chinese sausage and other goodies.
One of the best places to sit in and watch the late-night action unfold is at the hu tieu restaurants at the end of Nguyen Trai. Easily accessible from the backpacker hub of Pham Ngu Lao, these stalls all sell hu tieu nam vang and are frequented by a compelling mix of party people and bar workers looking for an end-of-shift feed.
Another good noodle option can be found at the other side of District 1 on Thai Van Lung where Osaka Ramen serves up bowls of delicious ramen noodles to a mixed crowd. Often rowdy, but usually good natured, the restaurant is a great place to wash down your food with jugs of sake.
For a more traditional western late night feast, try Pro Kebab on Tran Hung Dao near the intersection with De Tham or Long Phi on Bui Vien, which serves up surprisingly accomplished French fare until the wee small hours.
