Ha Long Bay isn't only about limestone karst scenery — the fresh seafood pulled from the bay is what the people of Quảng Ninh province are proudest of. Chả Mực (squid cake) is the signature local dish, recognised at a national level: fresh squid is hand-pounded with a stone mortar until smooth and sticky, then deep-fried until golden and crisp — a flavour you won't find anywhere else. The seafood markets along the bay and the restaurants of Bãi Cháy are stocked with ingredients caught almost every morning.
#1 Chả Mực — Hand-Pounded Squid Cake
Ha Long's Chả Mực is the defining food of Quảng Ninh province. Fresh squid caught in the bay is hand-pounded in a stone mortar until smooth and elastic, seasoned with black pepper, garlic, and fish sauce, then shaped into patties and fried in hot oil until the outside is golden and crisp while the inside stays pleasantly chewy. It's typically eaten with Bánh Cuốn (steamed rice rolls) or plain rice. The well-regarded Chả Mực Quảng Phong in the Bãi Cháy area is one of the go-to spots.
- Buy fresh from a market stall at Ha Long Market rather than pre-frozen packs
- Pairing it with Bánh Cuốn is the combination locals prefer most
- Vacuum-packed versions are available at the market to take home — they keep in the fridge for several days
#2 Halong Bay Grilled Oysters
Ha Long's oysters are harvested daily from aquaculture rafts in the bay, then grilled over charcoal and finished with a shallot sauce or a squeeze of lime and black pepper. The flavour is naturally rounded and lightly briny — a direct result of the clean bay water. The entire Bãi Cháy beachfront strip is lined with stalls selling grilled and fried shellfish, and prices here are significantly lower than what you'd pay aboard a cruise boat.
- Order oysters that are still tightly closed — a reliable sign they're genuinely fresh
- Try both the charcoal-grilled version and the lime-steamed version side by side to compare
- Night-market stalls are roughly 30% cheaper than the seafront restaurants
#3 Cháo Hà — Acorn Barnacle Porridge
Cháo Hà is a rice porridge made with acorn barnacles — small marine creatures that cling to the rocks along the bay's shoreline. The barnacles are marinated in fish sauce and pepper, stir-fried with onion, then stirred into simmering rice porridge and finished with coriander and cracked black pepper. The broth is rich and savoury, the aromatics fragrant — which is why this has long been a favourite breakfast among locals.
- Find it at local eateries inside the morning market; it rarely appears on tourist-facing menus
- Order it alongside fried Chả Mực for a proper local breakfast spread
- The flavour is mild and approachable — a good option if you find strongly flavoured seafood dishes overwhelming
#4 Sam — Horseshoe Crab
The horseshoe crab, known locally as "Sam," is an ancient marine animal found in the shallow waters of Ha Long Bay. Locals prepare it multiple ways — grilled over charcoal, stir-fried sweet-and-sour, steamed, or tossed into a salad. The meat has a flavour similar to regular crab but more intense, and the bright orange-yellow roe is especially rich. It ranks among the most unusual and worthwhile seafood experiences in Vietnam.
- Order it grilled or stir-fried with lemongrass and pepper to get the best out of the flavour
- It costs more than standard seafood — always ask the price before ordering
- It's seasonal: easiest to find during the rainy season, June through September
#5 Live Seafood on Ha Long Bay Cruise
One of the unexpected pleasures of an overnight Ha Long Bay cruise is the meal itself. Each boat's kitchen prepares seafood caught the same day — soy-steamed fish, salt-grilled prawns, curry-powder crab, and butter-fried squid are common. Eating dinner anchored among limestone islands is the kind of experience that's genuinely hard to replicate elsewhere.
- Choose a boat with an open kitchen so you can see food being prepared and feel confident about hygiene
- State your preferences before boarding — some vessels accept special requests in advance
- Watch for budget boats that charge extra for fresh seafood without disclosing it upfront — always check the price list first
#6 Bánh Cuốn Chả Mực — Steamed Rice Rolls with Squid Cake
Bánh Cuốn Chả Mực is the inseparable breakfast pairing for people in Ha Long. Thin, translucent steamed rice sheets are filled with minced pork, shallots, and wood ear mushrooms, then served alongside a piece of crispy fried squid cake and a sweet-sour fish dipping sauce. Sitting down to a bowl of this at a local breakfast shop in Ha Long early in the morning is about as authentic a local experience as it gets.
- Good Bánh Cuốn shops typically open at 6 am and close around 10 am — go early before supplies run out
- Order extra Chả Mực on the side for a more satisfying portion
- Prices are very reasonable — a complete breakfast runs around 30,000–50,000 VND (roughly US$1.20–2.00)
