Fish n' Grill brought the Cajun seafood boil to Dhaka and still does it better than anyone copying the format. A bucket arrives loaded with lobster, crab, mussels, calamari, and corn under a smoked-paprika and garlic-butter gravy heavy on cracked black pepper. Eating it is messy, communal, and takes about an hour.

What separates this kitchen is the supply line. Catch comes directly from Cox's Bazar, skipping the wholesale middlemen that cost most Dhaka restaurants two or three days of freshness. You pick your fish from the display on the first floor and the kitchen cooks it to order. The dining room seats over 60, which makes it one of the few genuinely good seafood rooms in the city that can take a group of twelve without a month of notice.

Almost everything at The Holy Crab is imported, which in Dhaka counts as a feature, not a compromise. Crab, shrimp, sea bass, and premium lobster arrive frozen at sea, so quality holds steady in a way locally sourced shellfish rarely manages in this city. The Louisiana-style preparations lean on butter and heat.

Turnover matters here more than at most places on the list. Go on a Thursday or Friday evening when the room is full and the kitchen is cycling through stock. A quiet Monday lunch is a noticeably different meal. The nautical decor is heavy-handed and the crab is worth it anyway.

Saltz applies French and Italian methods to Bangladeshi fish, and the results swing. The lobster thermidor is the most reliably good version in Dhaka, rich enough that one order feeds two people who have already eaten a starter. The pesto pangash is the more interesting dish and the less consistent one: when the herb balance lands it is the best thing on the menu, and when it does not the pesto flattens a delicate fish.

Order the seafood platter if it is a first visit. It samples four preparations for less than ordering them separately and tells you quickly whether the kitchen is having a good night.

The open kitchen at 138 East is the selling point and it earns the attention. You watch your lobster or prawns go from display to pan, which resolves the sourcing question that hangs over most seafood dining in this city. The room is elegant without being stiff, quiet enough for conversation, and reliably good for a date or an anniversary.

The menu runs long, and consistency follows the kitchen's load. Order early in the evening or late, and skip the busiest 8pm to 9:30pm window if you want the chef's full attention on a whole fish.

The most technically precise seafood cooking in Dhaka happens here. Pan-seared salmon comes out at the right temperature every time, the grilled lobster is handled by someone who has done it a thousand times, and the seafood risotto is properly loose. Nothing on the menu will surprise a well-travelled diner. Everything will be correct.

Service matches the room, formal and unhurried. This is where to take a client you need to impress, and an expensive place to satisfy a simple craving for fried fish.

Lake Terrace is a rooftop steakhouse that happens to cook seafood well. The calamari is properly tender and the jumbo prawns are the reason to come, not the steak the venue is named for. What you are really paying for is the view over the lake and skyline, and on a clear evening after the heat drops it justifies the trip from central Dhaka.

For anyone living in Uttara or Sector 7, this is the only serious seafood option within a reasonable drive.

Seven Hill sits on the seventh floor of DK Tower and does grilled fish and prawn cocktail with more precision than the price suggests. Portions are generous without tipping into waste. The room is dim and deliberately romantic, which works for a date and less well for a family with children.

The Artichoke plates carefully and cooks fish accurately. Seasoned diners will find nothing here they have not eaten before, and that is a fair trade for a kitchen that does not miss. Good for a group of four to six who want a proper meal without the formality of a hotel dining room.

Izumi is the most serious Japanese kitchen in Bangladesh and prices accordingly. Sushi, sashimi, and tempura are all handled by people trained to do them properly, and the fish quality justifies the premium in a way that most Dhaka Japanese restaurants cannot claim. The room is quiet, the service unhurried, and the bill substantial.

If you eat sashimi in Dhaka, eat it here or at Ginza. The gap between these two and everywhere else offering raw fish in this city is wide enough to matter for food safety, not just for taste.

Ginza builds its menu around raw fish quality and mostly delivers. Sushi and sashimi are the reason to come; the cooked dishes are pleasant and forgettable. Service is warm without hovering, and the fourth-floor room suits a quiet dinner for two better than a group celebration.

C'Zar runs generous seafood platters of prawns, fish, and calamari alongside a Japanese-influenced sushi section. The strength here is range: a group where two people want sashimi and two want grilled prawns can all eat well. Service stretches at peak hours, so a 7pm booking beats a 9pm one.

The steamed fish with lime and chilli at Krua Thai is one of the best seafood dishes in Dhaka at any price. The kitchen controls heat properly, so the chilli sharpens the fish without burying it. Grilled lobster is the other draw and costs considerably more.

Tell the staff your spice tolerance honestly. The default heat level is calibrated to Thai expectations, not Dhaka ones, and the kitchen will adjust without complaint if you ask before ordering.

Thai Signatures seasons harder than Krua Thai and rewards people who want it. Spicy crab and crispy prawns are the signature dishes, both generous enough that three plates feed four people. Authenticity is prioritised over presentation, which suits the food.

Seafood at Yum Cha District lives inside the dim sum, not on a plate of its own. Shrimp dumplings are the standout, and the complimentary ginger tea has a following of its own. Come for a long lunch over tea, not for a seafood dinner.

A broad pan-Asian menu covering grilled prawns, fish curries, and lobster preparations with careful seasoning across all three. The value here is range for a group that cannot agree on a cuisine.

Raffinato does seafood pasta and grilled fish with proper Italian technique. Fish quality is good; sauces sometimes push past the fish underneath them. Ask for the sauce light on any pasta with a delicate white fish and the kitchen will oblige.

Deshi Shad has no ambition beyond cooking local fish properly and charging little for it, and that focus makes it one of the most satisfying meals in this guide. Fish, prawns, crab, and lobster arrive in familiar Bengali preparations without garnish or ceremony. Freshness is consistently high because turnover is fast and the menu is short.

Anyone judging a restaurant by its interior will be unimpressed. Anyone judging by what arrives on the plate for under a thousand taka will come back.

Biye Bari cooks river fish, prawns, and lobster in a style borrowed from Bengali wedding feasts, updated slightly for a restaurant setting. Portions satisfy, prices are fair for the quality, and the plain decor keeps the focus where it belongs. This is the closest thing on the list to eating at a well-run Bangladeshi home.

The Smokes bridges Bengali seafood curries and international lobster and crab dishes without doing either badly. The vegetarian section is unusually good for a seafood-forward restaurant, which makes this a workable choice for a family where not everyone eats fish.

Cafe Rio's Uttara branch buys locally and cooks simply: grilled fish, prawn masala, and fish curry, all handled with care. Casual enough for a family lunch, cheap enough to be a regular stop, not an occasion.

FishValley grills and fries prawns and crab without experimenting, and the flavours land. For anyone in south Dhaka who does not want to fight traffic to Gulshan, this is the practical seafood answer.

Operating in 11 countries and among the longest-running seafood restaurants in Dhaka, Manhattan Fish Market sells consistency. Fish and chips is done properly, the Dory fillets come out crisp outside and tender inside, and portions are generous. Nothing here will excite a serious eater. Everything will please a table of eight with mixed tastes.

The Singapore-origin chain runs a seafood-only menu with a nautical theme and Mediterranean leanings. Fried calamari and fish and chips are reliable. Creative flair is minimal and the family-friendly room is bright and easy. Drinks skew sweet.

Half buffet, half à la carte, on level 11 of R Plaza. Grilled shrimp and steamed fish are consistently well made, and the lobster thermidor holds up. The buffet rewards selective eating: three good dishes returned to twice beat twelve mediocre ones sampled once.

Wooden interiors and low lighting make Rustic Eatery feel more personal than most Banani restaurants. Grilled fish, squid curry, and lobster thermidor are all plated thoughtfully without overreaching. Good for a small group that wants to actually hear each other.
