Ha Long eats like the fishing region it is: fried squid cake for breakfast, clams you will not find further south, and shellfish sold by the kilo. Here is what to order, where to order it, and how to avoid the tourist-price trap.
Ha Long feeds itself the way a working fishing region does. The bay produces shellfish that never travel far, the markets sell them alive, and the one dish everybody here is genuinely proud of is squid, pounded by hand and fried. The short answer to what to eat in Ha Long Bay is that squid cake comes first and the shellfish comes second, and that if you arrive expecting Hanoi street food you will be mildly disappointed while anyone arriving hungry for seafood will do very well.
Chả mực, the squid cake worth planning around
Fresh squid is pounded by hand rather than blitzed in a machine, seasoned with pepper, formed into flat patties and fried until the outside is golden. The texture is the point: springy and dense, nothing like a fish cake elsewhere. Locals eat it hot, most often with xôi, steamed sticky rice, or tucked into bánh cuốn, thin steamed rice rolls. It is also the standard gift to take home, sold vacuum-packed and best kept cold on the journey.
Ngán, the clam nobody warns you about
Ngán is a mud clam particular to this stretch of coast, with a much stronger flavor than the small clams you meet elsewhere in Vietnam: sweet, faintly bitter at the front, lingering. Grilled in the shell is the easiest introduction. It also goes into a rice porridge that locals treat as restorative food, and, more memorably, into rượu ngán, rice liquor mixed with the juices of the clam. It arrives murky and tastes exactly as strange as it looks. Try a small glass for the story.
- Grilled in the shell, the cleanest way to taste it
- Cháo ngán, a savory rice porridge, good on a cold morning
- Rượu ngán, the local clam liquor, a small glass is plenty
Sá sùng, the expensive one
Sá sùng is a sandworm dug out of the tidal flats at low tide, cleaned and dried. Cooks here drop it into broth to give a clean natural sweetness that no amount of seasoning reproduces, and dried pieces roasted until crisp are a beer snack. Digging it is slow, skilled work, which is why it is among the priciest things in the market and why a shop selling it very cheaply is probably not selling sá sùng.
The rest of the shellfish
Beyond the local specialties, most of what you eat here came out of the bay that morning. Tu hài, a large burrowing clam similar to geoduck, is usually grilled with spring onion oil and peanuts and is one of the easier introductions for a nervous eater. Flower crab and mud crab are steamed with beer or stir-fried with tamarind. Mantis shrimp, called bề bề, look prehistoric and taste sweet. Oysters, sea snails, grouper and cobia round out most menus.
- Tu hài, grilled with spring onion oil, crisp and sweet
- Crab, steamed with beer or cooked in tamarind sauce
- Bề bề, mantis shrimp, messy to eat and worth it
- Oysters, sea snails and whole grouper or cobia, steamed, grilled or in a hotpot
Where to eat
Bai Chay, the tourist side of the harbor, has the concentration of seafood restaurants and the night market, and it is where you will end up on a shore night. For something closer to how locals shop, cross the bridge to Hon Gai and the main Ha Long market, where you pick from the tanks and some stalls will cook what you choose on the spot. The rule that holds everywhere is to follow Vietnamese diners rather than tour buses.
- Bai Chay: the biggest choice of seafood restaurants, plus the night market
- Hon Gai and Ha Long market: buy from the tanks, some stalls cook it for you
- Eat seafood in the evening, when the day's boats have come in
- A busy room full of local families beats an empty one with an English sign
Prices and paying
Shellfish is priced per kilo and varies by species and season, so a meal can cost anything from modest to eye-watering depending on what you point at. As a planning estimate, budget roughly 800,000-1,500,000d per person, around US$32-60, to cover food and attraction tickets across a three-day trip. Carry cash: market stalls and smaller restaurants often do not take foreign cards, and 100,000d is roughly US$4 if you need a quick conversion.
Ask the price per kilo before anything is weighed, and watch the scale. Confirming the total before the kitchen starts cooking is completely normal here and no one will find it rude.
What to eat in Ha Long Bay if you do not eat shellfish
This is the honest weak spot of the region and it catches people out. A coastal city whose whole reputation is molluscs is a difficult place to be allergic, vegetarian or simply squeamish. It is not hopeless, but you have to steer. Almost every seafood restaurant also grills pork and chicken, cooks morning glory with garlic, and will make fried rice or a plain noodle soup on request. Chả mực is squid rather than shellfish, so a shellfish allergy does not rule it out, though a kitchen that fries squid cakes all day is not a low-risk kitchen for a severe allergy. Standard Vietnamese dishes travel here too: phở, bánh mì, the split baguette with pate and pickled vegetables, and bún, rice vermicelli in various forms, all turn up in Bai Chay and Hon Gai. What you should not do is book an overnight cruise and hope. The galley shops for the exact headcount, the menu is set seafood, and telling them on the pier is too late.
Breakfast, and what a day of eating costs
Breakfast here is not a hotel buffet unless you make it one. The local version is chả mực with xôi, a plate of steamed sticky rice, eaten hot from a stall before nine, or a bowl of noodles. It costs very little and it is the best value meal of the day. Dinner is where the money goes, because shellfish is priced by weight and the bill depends entirely on what you point at.
- Street or market breakfast: around 30,000-70,000d, roughly US$1.50-3
- A simple rice or noodle lunch away from the tourist strip: around 50,000-120,000d, roughly US$2-5
- A seafood dinner for one at a Bai Chay restaurant: around 300,000-700,000d, roughly US$12-28, and far more if you order crab and tu hài freely
- A day of eating well without going wild: around 400,000-900,000d, roughly US$16-36
- Across a three-day trip, budget roughly 800,000-1,500,000d per person, around US$32-60, for food plus attraction tickets
Eating around a day trip from Hanoi
If you are coming out from Hanoi for the day, the transport leg eats your meal times. The drive is about 165km (roughly 100 miles) and takes 2.5 to 3 hours each way on the expressway, so a bus leaving the Old Quarter at eight puts you on a boat by late morning, and lunch is the set meal served on board as the boat leaves the harbor. That is fine, but it is not the food you came for. The realistic version is to make dinner the meal that matters: get back to shore by late afternoon, eat in Bai Chay when the day boats have come in and the seafood is at its freshest, and take a later bus back. Better still, stay a night. Almost everything worth eating here is an evening meal.
When the weather turns
A closed bay is the most likely disruption to any trip here, and it is also the best food day you will get. When the port authority suspends sailings for rough seas, which happens most often between July and August, the restaurants carry on as normal and the town is suddenly not competing with a boat schedule. Cháo ngán, the rice porridge made with the local mud clam, is exactly what a cold wet morning calls for. A seafood hotpot at a table full of local families in Hon Gai is a good way to lose three hours. If it is the winter fog rather than a storm, the boats still sail and the market still sells, so nothing changes except the view.
How this fits two weeks of eating in Vietnam
Vietnamese food changes materially every few hundred kilometers, and this stretch of coast is the shellfish chapter. Hanoi, three hours west, is the place for bún chả, phở and bánh cuốn. Hue and Hoi An in the center bring chilli heat and their own noodle dishes. Ho Chi Minh City and the Mekong Delta are sweeter and more herb-heavy. Ha Long is where you eat things that do not travel: ngán, sá sùng, tu hài and squid pounded by hand that morning. Treat it as one distinct meal or two inside a much longer eating itinerary, order the two or three local specialties rather than a general seafood spread, and you will not leave feeling you ate the same food twice.
A few things to know
- Tell your cruise operator about allergies or a vegetarian diet when booking, not on board
- Chả mực and dried sá sùng are the standard souvenirs, buy from an established shop rather than a stall by the pier
- Prices listed on a board are per kilo, not per plate, unless it says otherwise
- Breakfast in town means chả mực with sticky rice or a bowl of noodles, not a hotel buffet
- If shellfish is not your thing, most seafood restaurants also grill pork and cook standard rice dishes
