Ask anyone from Uthai Thani what you have to eat when you visit, and the first answer is almost always "river fish." The Sakae Krang River runs right through town and has been a cage-farming spot for fish for decades. The most famous one is giant gourami — firm, chewy flesh that's rich without being greasy. What surprises a lot of people is that it barely has any muddy taste at all, because the water keeps flowing and the farmers are picky about feed.
Sakae Krang basin giant gourami is registered with GI (geographical indication) status by the Department of Intellectual Property — the only giant gourami in Thailand to earn the mark, because its taste and texture are tied to this specific stretch of water. Put simply, eating it in Uthai Thani gets you a flavor you can't get anywhere else.
Know the Sakae Krang river fish before you order
Before you open the menu, knowing the fish makes ordering more fun. There are only a few popular species in the Sakae Krang River, and each one suits a different way of cooking.
- Giant gourami (pla raed) — the star of Uthai Thani. Firm, sweet flesh, large in size, great salt-grilled, garlic-fried, or topped with chili. This is the GI fish.
- Red-tail catfish (pla kang) — soft, silky flesh that's not too fatty, delicious in tom yum or blanched with dipping sauce. Most places make tom yum red-tail catfish a signature dish.
- Butter catfish (pla neua on) — thin, soft flesh almost like butter, great deep-fried crispy or in curry. Melts in your mouth.
- Clown featherback (pla krai) — popular scraped and made into bouncy fish cakes, fragrant with curry paste.
- Soldier river barb (pla ma) — firm flesh with a mild, gentle flavor, good steamed or in tom yum. Perfect if you like plain, meaty fish.
How to order for the best value
A big giant gourami is priced by weight, so if there are just two of you, order a small one or split half a fish — that's plenty. Then add a red-tail catfish dish or a plate of veg and you'll be comfortably full. No need to order a fish so big you can't finish it.

Half a day with a local who knows the lanes — or cooking a dish yourself — teaches you more than just eating. Book ahead on Klook or GetYourGuide.
River fish you have to try — what to order
Salt-grilled giant gourami
The real headliner. The whole fish is packed in salt and grilled over coals, so the flesh inside comes out juicy and naturally sweet with barely any seasoning. Pull it apart and eat it with a spicy seafood dipping sauce — this is the dish people drive a long way to Uthai Thani for.
Tom yum red-tail catfish
A bold, balanced sour-spicy tom yum broth with soft, silky red-tail catfish that's just fatty enough. Some places add termite mushrooms for extra aroma. Slurped hot with steamed rice, it's a lunch that just works.
Garlic-fried giant gourami
Fried whole until the skin is crispy and topped with fragrant fried garlic, while the flesh inside stays soft and juicy. It's the hit dish at well-known spots like Nok Noi and Sala Coke. Kids can eat it since it isn't spicy.
Giant gourami fried with fish sauce / chili
Fried crispy then topped with sweet fish sauce or stir-fried chili — sweet first, salty after. Goes down easy with rice, and it's a dish you can order alongside the grilled fish without the flavors clashing.
Clown featherback fish cakes
Fresh clown featherback flesh scraped and pounded with curry paste, then fried until bouncy and chewy, fragrant with kaffir lime leaf. Snack on it dipped in sweet chili sauce while you wait for the big fish — people usually order this as a starter in Uthai Thani.
Blanched red-tail catfish with dipping sauce
Red-tail catfish sliced and blanched just until cooked, then dipped in spicy seafood sauce — you get the fresh fish flavor in every bite. Great for anyone who likes fish without heavy seasoning.
Choo chee / jungle curry catfish
Sweet, rich coconut choo chee curry poured over fried red-tail catfish, or a bold jungle curry with no coconut milk. Order either one to spoon over rice and you've got a full meal.
Crispy fried butter catfish
Thin-fleshed fish fried until the whole thing is crispy, fun to munch like a snack but still full of that river-fish flavor. Kids love it because there are no annoying bones.
Riverside spots Uthai Thani locals really go to
Part of the charm of eating fish in Uthai Thani is sitting at a table right on the Sakae Krang River, watching the fish cages and houseboats while you eat. Many of these places have been open for decades and have become the names locals meet up at. These are the ones reviews mention most.
Nok Noi Garden Restaurant
A long-running spot open for over 50 years, right on the Sakae Krang River in the center of town on Si Uthai Road, Uthai Mai sub-district. The legendary dish is garlic-fried giant gourami. Open daily 10:00–20:00.
Sombat Chuan Chim
A riverside place in the Ko Thepo area with a relaxed feel, known for salt-grilled giant gourami, gourami fried with fish sauce, tom yum red-tail catfish, choo chee catfish, and jungle curry fish. Open daily 10:00–20:30.
Sala Coke
A fish restaurant going over 30 years in the Tha Sung area, not far from Wat Tha Sung. Garlic-fried giant gourami, clown featherback fish cakes, and tom yum red-tail catfish with termite mushrooms, around ฿101–250 per head. Open 9:00–21:00.
Krua Sakae Krang
A raft/riverside spot on the Sakae Krang with a chill vibe. The dishes people order most are crispy morning glory salad, garlic-fried giant gourami, and blanched red-tail catfish. A good stop after visiting Wat Tha Sung.
Krua Khung Samphao
A riverside spot on the Sakae Krang not far from Wat Tha Sung, with an open river view — good for a long, leisurely fish meal in the cool breeze. Another Tha Sung-side option reviewers like.
Best time to go
Riverside fish restaurants get packed at holiday lunchtimes and in the evening. If you want a good riverside table, go before 11:30, or in the evening before 17:30 — cooler and breezier, and no long wait. A big fish takes time to grill at some places, so order a snack to tide you over while you wait.
Eat fish like a local for the best value
- Order a whole fish, then pick the cooking method — tell the restaurant whether you want it grilled, fried, or in tom yum. The same fish can be done several ways, and a big giant gourami can be grilled on one half and fried on the other.
- Start with salt-grilled giant gourami — if it's your first time, order this dish first to taste the truest fish flavor, then add tom yum or fried dishes.
- Ask the price per kilo before ordering — fish is priced by weight, so ask the per-kilo price and the weight of the fish you'll get, and you won't be surprised at the bill.
- It's better value with a group — a big fish is made for sharing. With 4–6 people, order one giant gourami, one red-tail catfish dish, some veg, and fish cakes, and it averages just a few hundred baht per person.
