Vietnam has about 3,260 km of coast and a fishing fleet working most of it, so seafood here is fresh, plentiful and cheap. Seafood is also the one thing on a Vietnamese menu where visitors regularly pay several times what they meant to. The reason is always the same: the kitchen sells it by weight.

Where do you actually eat it?

On the coast, at the plain places. Da Nang, Nha Trang, Quy Nhon, Phu Quoc and Con Dao all land their own catch. The best meals come from restaurants that look like a concrete floor, plastic chairs and a row of tanks.

The rule that works: eat where the tanks are full and the menu runs to 2 pages rather than 12. A place with photographs of every dish and a menu in four languages is buying its seafood the same way you would.

Hanoi and Ho Chi Minh City eat well, but they eat freight. The difference between coastal and inland seafood in Vietnam is larger than the distance suggests.

The shellfish end of the same menu has its own restaurants and its own hours: the snail places that open after dark.

How does the pricing actually work?

By weight, and this is where the money goes. The board usually quotes per 100 grams rather than per kilo, which makes every number read as a tenth of the real price. A lobster shown at 500,000 is 5,000,000 dong a kilo. A 700 g animal is 3,500,000 of them, roughly $135 at about 26,000 dong to the dollar.

Four questions, asked before anything is cooked:

  1. What is the price per kilo?
  2. What does this one weigh?
  3. Is that the live weight or the cleaned weight?
  4. What is the cooking charge on top?

Have the total written down or shown on a calculator. This is completely normal here and nobody is offended by it. A place that will not give you a number before cooking has told you what kind of place it is.

What should you order?

Whatever came in that morning, cooked simply. The standards are grilled scallops with spring onion oil and crushed peanuts, salt-and-chilli prawns, clams steamed with lemongrass, and grilled squid.

Crab and lobster are where the bill goes and rarely where the pleasure is, because the tank sets their price rather than the plate. A table of scallops, clams and prawns costs a fraction and eats better.

Order in rounds rather than all at once. The kitchen sends each dish as it finishes, so a table that orders everything at the start receives everything at once.

Is it safe?

Cooked and hot, yes — as safe as anything you will eat in Vietnam and safer than most. Shellfish grilled to order in front of you is a low-risk meal.

The risks are the familiar ones and none of them is the grill. Raw shellfish, anything that has been sitting warm on a buffet, and the herbs and ice served alongside are where the food safety guide puts the actual problem.

The islands carry one extra note. Con Dao and Phu Quoc are further from a major hospital than they feel, which is an argument for ordering more conservatively there than in Da Nang.

What about the fish sauce?

Fish sauce is the point, and Phu Quoc is where a great deal of it is made. Nuoc mam from the island holds a protected designation of origin. Producers ferment anchovies with salt in wooden vats for 12 months or more, and several factories run visits.

A vegetarian meets the fish sauce problem at its most unavoidable here. Fish sauce is in almost every dipping sauce on a seafood table, including the ones that look like chilli and lime.

When is it best?

In the dry season on whichever coast you are on, which is not the same month in both places. The central coast lands its best catch and calmest boats from roughly March to September. The southern islands run the opposite calendar, November to April — a gap of about 6 months between the two.

The six-month split governs the whole trip, not just dinner — the beaches guide sets out which shore works when.

FAQ

Where is the best seafood in Vietnam?

The central coast and the islands. Da Nang, Nha Trang, Quy Nhon, Phu Quoc and Con Dao all land their own catch, and the good places are the plain ones on the beach road rather than the restaurants with English menus and photographs. Hanoi and Saigon eat well but eat freight.

How is seafood priced in Vietnam?

By weight, almost always, and usually per 100 grams rather than per kilo on the board. That is where the bill goes wrong: a lobster priced per 100g reads cheap and arrives expensive. Ask for the price per kilo and ask what the animal weighs before it is cooked.

How do you avoid being overcharged for seafood?

Ask four things before anything is cooked: the price per kilo, the weight of what you chose, whether it is priced live or cleaned, and what the cooking charge is. Get the total in writing or on a calculator. A place that will not do this is telling you something.

What seafood should you order in Vietnam?

Whatever came in that morning, cooked simply. Grilled scallops with spring onion oil and peanuts, salt-and-chilli prawns, steamed clams with lemongrass, and grilled squid are the standards. Crab and lobster are where the money goes and rarely where the pleasure is.

Is seafood safe to eat in Vietnam?

Cooked and hot, yes, and it is among the safer things you will eat. The risks sit where they always do: raw shellfish, anything sitting warm, and the herbs and ice served beside it rather than the grill itself.
