Bangkok’s best Thai-caught fish omakase and sushi

Tucked inside Vapor restaurant at Nichada Thani, Kaijin is the closest thing this scene has to a flagship. Its ‘freshly caught, delicately crafted’ philosophy celebrates the seasonal character of Thai fish. Chef Natakorn Changkreaw and his team head to sea most weeks to hook their own catch, shaping  each menu around whatever comes back. Natakorn created Kaijin to challenge the idea that Thai ingredients cannot compete with the world’s finest imports.

Past highlights include Santoryu, an opening course of giant grouper gill styled as a ‘pseudo shark fin’; fishbone marrow with black truffle; and fried Java barb served on an edible rod. A three-way sashimi plate compares tachiuo, rainbow runner and bigeye trevally, their sashimi-ready quality made possible by ikejime processing, while aburi goliath grouper nigiri is sprayed with single malt before dry-ageing.

39/1257 Samakkee Rd, Nichada Thani, Nonthaburi. Friday-Sunday, 6 pm-midnight.

Hidden near Lak Si Red Line station, Iki's point of difference is less the fish itself than what happens before it reaches the plate. Instead of serving it straight off the boat, the kitchen bleeds each fish to remove any fishy edge, wraps it in moisture-wicking ageing paper and dry-ages it under controlled temperature and humidity. The team says the process produces firmer texture, a sweeter finish and deeper umami than fish sliced immediately.

It is a very different philosophy from Kaijin's hook-and-line immediacy or Dailyfish's boat-to-table approach. Iki bets on patience, arguing that good ingredients need time and attention at every stage – not freshness alone. 

100/216 Kamphaeng Phet 6 Soi 5 Yaek 2-7, Thung Song Hong, Lak Si, Bangkok.  Near Lak Si Red Line Station. Tuesday-Thursday and Saturday-Sunday, 3 pm-10 pm; Friday, 3 pm-midnight; closed Monday.

Run from a house on Bang Saen–Ang Sila Road by two young chefs, Dailyfish is Chonburi's answer to the trend – and reportedly Baeng Saen’s first Thai fish omakase. One chef catches the day's fish himself, so the nine-course menu does not exist until he returns from the water. Expect yellowtail barracuda, mixed white-fish sashimi, sea bream and a species known locally as ‘chom-ngam’ – loosely, ‘pretty face’ fish – served as sashimi, sushi and carpaccio, or worked into fish-bone broth with basil and tomato.

Standouts include squid with pomelo and a house-made yuzu sauce aged for more than a year, plus a whole baby squid so fresh it has never touched fresh water. At B699–799 net per person, excluding drinks, it is excellent value for a catch-of-the-day omakase.

Set inside the Smash Gym building in Kaset-Nawamin, Ayoi proves the trend does not need fine-dining trappings. There is no grand sourcing story or , fisherman-chef narrative – just a neighbourhood shop leaning into Thai-caught fish because it is fresher and cheaper than imported alternatives. Its daily sashimi platter rotates through eight to 12 varieties, mostly Gulf of Thailand white fish such as local sea bass and needlefish, alongside a ‘special of the day’ fish cart, conventional sushi, ramen and gyudon.

More unusual orders include bluefin tuna eyeball steamed in soy sauce and tuna bone served with the remaining meat still attached. 

Kaset-Nawamin, inside the Smash Gym building. 10.30 am-10.30 pm daily.

Near the Thai Chamber of Commerce, CURING keeps things simple: sashimi and sushi made from Thai marine fish, with no fusion detour or fine-dining framing. Its signature eight-piece Thai sea fish omakase sushi set costs B120, making it one of Bangkok’s cheapest ways to try the style.

This is a small, casual and delivery-friendly operation – closer in spirit to Ayoi than Kaijin, and proof of how far the local-fish idea has travelled into everyday dining.

Near the Thai Chamber of Commerce, Vibhavadi Rangsit Soi 2. Monday, Tuesday, Thursday, Friday and Saturday, 6 pm-late; closed Wednesday and Sunday.

This budget-friendly sushi bar near BTS Wongwian Yai shapes each piece to order, while a daily-changing ‘special menu’ spotlights Thai sea-fish sashimi, including sea bass sliced almost translucent. 

With little conventional press, Musashi has grown largely through TikTok and Instagram word of mouth – another sign that local-fish sushi has reached well beyond high-end omakase counters.

80/1 Krung Thon Buri Road, Bang Lamphu Lang, Khlong San. Daily, 4-11 pm.

This Hua Hin sushi restaurant explicitly pairs Japanese technique with local Thai ingredients. Public details on its chefs, Thai species, signature dishes and pricing remain limited, so it is best treated as one to watch rather than a fully documented stop on the list. 

6/8 Hua Hin 51 Alley, Hua Hin, Prachuap Khiri Khan. Daily, 5 pm-midnight.

Not a restaurant, but arguably the most important name in this feature. Gyotak (เกียวทัค ปลาไทยหัวใจญี่ปุ่น, roughly ‘Thai fish, Japanese heart’) is run by Takuya Okura, a Japanese fish handler in Hua Hin who comes from a family of fish traders and learned his craft in Japan's fish markets. He is quick to say he is not a chef, just someone who knows how to select and handle a fish. His conviction runs through this scene: almost any Thai species, treated properly, can be served raw to a standard rivalling its Japanese equivalent.

What sets Gyotak apart is the safety work behind the product. Its fish is reportedly tThailand’s first sashimi-grade seafood to be laboratory-verified free of pathogens commonly associated with tropical waters – long one of the main objections to serving Thai fish raw. Everything is processed using ikejime and korijime, or cold-seawater slaughter, the same handling standards used by chefs at Kaijin and Musashi..

Gyotak has no permanent dining room, but its fish appears on restaurant menus through collaborations and pop-ups.
