Phu Quoc Seafood Prices: Kilos, Portions and a Worked Crab Bill

One kilogram is 1,000 g; one lạng is 100 g. A quote of 65,000 VND per lạng equals 650,000 VND/kg. A sign showing 65 without its unit is therefore not enough to compare with another sign showing 650. Ask the server to point to the unit and write the weight being purchased. A calculator is useful here because it makes both people look at the same amount.

Price per plate is another format. It can include sauce, vegetables or cooked shellfish without promising a kilogram of raw material. A menu photograph does not define a portion’s weight. If the comparison matters, ask whether the plate has a specified quantity. Otherwise compare it as a prepared dish, with its own serving size and preparation.

Whole weight includes shell, bone or other parts you will not eat. A larger whole fish may feed a table well, but buying more whole weight is not the same as buying that amount of fillet. Keep this distinction in mind when the group is deciding between two crabs, a whole fish and a smaller prepared plate.

Nhà Bè Khánh Hào is in Rạch Vẹm, not Hàm Ninh. Its à la carte menu, read on 19 October 2026, lists steamed crab at 65,000 VND/100 g (650,000 VND/kg) and steamed rice at 30,000 VND per portion. Using that menu for arithmetic, a selected 600 g crab would cost 0.6 × 650,000 = 390,000 VND. Add one rice portion and the subtotal is 420,000 VND before any other dishes, drinks or additions.

If the chosen crab instead weighs 800 g, the crab line becomes 520,000 VND at the same kilogram price. The extra 200 g adds 130,000 VND. Nothing about the unit price changed. This is why agreeing a budget without seeing the selected weight can still produce a surprise, even when the seller uses the price you were shown.

That restaurant also markets set products. A set including a boat journey and several dishes is not comparable line for line with this crab-and-rice example. Start by choosing whether you want the transport-and-meal product or the individual dishes. Then read the inclusions of that product rather than moving the cheapest number from one menu format into another.

Crab, lobster, mantis shrimp and ordinary prawns are not interchangeable just because they sit in neighbouring tanks. Size and grade can change the quote within one type too. Ask for the name of the actual selection and its price, not simply the restaurant’s cheapest “seafood” figure. When names are difficult, keep the selected item, menu line and written order together.

Steaming, tamarind sauce, garlic frying and hotpot are different kitchen tasks. Some menus price a cooked dish directly; others quote raw seafood and add preparation. Ask whether your chosen method is included and whether splitting a fish into two dishes adds another charge. A clear answer belongs before the fish is cut, not after it has become two finished plates.

The rest of the table also affects value. Crab takes time to shell and may not be the filling centre of a meal for hungry children. Rice, vegetables and soup can be useful companions. Decide which seafood is the treat and which other dishes make the meal complete, rather than treating an ever-larger tank order as the only way to feed the group.

A useful order might read: selected crab, 0.6 kg, 650,000 VND/kg, steamed, 390,000 VND; rice, one portion, 30,000 VND. This is an illustration based on the menu above, not a receipt from a visit. Add any cooking or service charges that the restaurant says apply, with their amounts or calculation. Keep drinks and optional extras on their own lines.

Seeing the weighing and asking for a written order are normal purchase steps, not accusations. Do not handle live animals to test them yourself. If a different specimen is proposed after weighing, ask for its weight and revised amount. A simple substitution should not break the link between what you chose and what the kitchen received.

Fish soup, seafood noodles, crab fried rice or a named grilled-fish dish can be easier to budget than live selection. As a separate example, the September 2026 Clubhouse menu at Premier Residences Khem lists crab fried rice at 350,000 VND, with its stated service and applicable VAT included. That is a prepared rice dish in a hotel restaurant, not a benchmark for a kilogram of crab in a village.

Choose the format that fits the meal you want. A single traveller can enjoy a bowl without buying a whole fish; a family can share a seafood main alongside ordinary dishes. Use the Food Prices guide for the day’s overall food budget, and this guide for the unit and calculation inside the seafood purchase.
