There is an unwritten rule in Vietnam: if the place looks too clean and too expensive, you're probably in the wrong spot. The best things are eaten on plastic stools, in the steam of a pot that's been simmering since 5 a.m., for the equivalent of 1.50 €.

This guide does not claim to be exhaustive — Vietnamese cuisine is one of the most complex and most regionalized in Asia. It aims to make you hungry, and perhaps, incidentally, help you understand why Vietnamese people do business the way they eat.

The essentials, in order of urgency

Bánh mì — the baguette that traveled and no longer looks like anything

The bánh mì is a Vietnamese baguette inherited from French colonization, lighter and crispier than the original. Filled with pork pâté, slices of homemade cold cuts, pickled vegetables (sweet and sour carrot and daikon), cilantro, chili and a mysterious sauce according to the vendors.

It's one of the best sandwiches in the world. This is not an opinion, it's a widely accepted fact.

The best bánh mì can be found from vendors on bicycles or mopeds, often posted in the same spot for 20 years. In Hội An, the queues in front of Bánh Mì Phương (2B Phan Châu Trinh) testify to the sandwich's worldwide reputation. In Hanoi, look for small kiosks in the alleyways of the old town around 11:30 a.m.

Variation not to miss: bánh mì trứng — with a fried egg, all assembled before your eyes. Average price: 15,000 to 25,000 dongs (0.60 to 1 €).

Bún bò Huế — phở has a rival, and it comes from Central Vietnam

If phở is the ambassador of Vietnamese cuisine abroad, bún bò Huế is what Vietnamese people eat when they really want to treat themselves.

A soup of thick rice vermicelli, in an intense beef and lemongrass broth, with slices of shank, pork meatballs and — for the adventurous — a piece of blood pork mortadella specific to Huế. Spicy, fragrant, complex.

Born in Huế, the former imperial capital of Vietnam, this soup carries all the culinary sophistication of a city accustomed to cooking for emperors. It has spread throughout the country but remains unmatched in its city of origin.

Practical tip: ask for bún bò Huế "đặc biệt" (special) to get all the toppings. And be prepared — it's spicy.

Bánh xèo — the crêpe that crackles

Bánh xèo means "crêpe that hisses" — it's the sound it makes when the batter hits the very hot oily pan. A thin and crispy crêpe made with rice flour and turmeric, filled with shrimp, pork, bean sprouts and green onions.

The technique for eating it: you place a piece of crêpe on a lettuce or mustard leaf, add fresh herbs (mint, perilla, dill depending on the region), roll it up, dip it in the sweet-sour fish sauce.

It's one of the most interactive and friendly culinary experiences in Vietnam. Perfectly suited to a meal shared between strangers, which is often the best way to eat in Vietnam.

Chè — the dessert category that defies Western understanding

The word chè covers an entire family of Vietnamese desserts made with legumes, jellies, fruits, tapioca pearls, coconut cream and crushed ice. A chè shop menu can have 30 items.

A few recommended starting points:

Chè ba màu (three colors): mung beans, red beans and pandan jelly on crushed ice with coconut milk. Fresh, sweet, very photogenic.
Chè chuối: banana and tapioca in hot coconut milk. Simple and comforting.
Chè thái: rich version with lychees, jelly, corn, durian and coconut cream. For dessert adventurers.

Chè is eaten on the street, in plastic bowls, often in the late afternoon when the heat subsides a bit. It's a social ritual.

What street food teaches about Vietnamese business

This is where I wanted to go.

Vietnamese street food operates on a simple principle: specialization and reputation. A bánh mì vendor sells only bánh mì. A phở restaurant makes only phở. Sometimes for two or three generations. Quality is maintained because reputation is the only advertising that matters in a country where word of mouth travels fast.

The suppliers that CNL Sourcing works with often operate the same way. A workshop that has been making bamboo for 30 years knows how to make bamboo. It doesn't diversify, doesn't overpromise, doesn't sell you what it can't do. Business relationships in Vietnam are built on this honesty — and it takes time to establish, because it requires that we truly know each other.

Maybe that's why having someone on the ground — someone who speaks the language, who eats in the same restaurants, who understands the codes — changes everything.
