What is gwangeo-hoe (flatfish sashimi)?
Gwangeo (flatfish sashimi) is the same fish as neobchi — it’s just two different names for the same species! In Japan, it’s called "hirame" (olive flounder), and it’s one of the most popular white-flesh sashimi fish in Korea. It has a flat body, and funnily enough, both eyes are on one side of its head. That’s because it lives flat on the ocean floor!
The biggest charm of this sashimi is its springy, pleasantly chewy texture. The more you chew, the more flavor comes through — once you try it, you’ll keep reaching for more. It’s not heavy or greasy, so even first-time sashimi eaters can enjoy it comfortably.
In Korea, this fish is often called the "king of sashimi." In Japan, hirame is treated as a premium delicacy. That tells you just how special it is!
The waters off Yeonhwa-ri on the east side of Busan are particularly special because warm and cold currents meet here. Fish raised in these waters develop firmer flesh and deeper flavor!
3 reasons this fish is special here
Hand-selected one by one
Every morning, live fish arrive and are inspected by eye and by hand. Only those with clear eyes, firm flesh, and lively fins make the cut. Anything below standard gets sent back immediately!
Prepared to order from the tank
Nothing is pre-sliced here. When you order, the fish is pulled straight from the live tank and prepared on the spot. That’s why the texture stays so springy and firm!
Chosen by a 51-year veteran
The restaurant’s haenyeo (female diver) mother has been diving for 51 years. She can tell quality by touch alone — whether the eyes are clear, whether the fins have strength. Only fish that pass her inspection make it to your table!
How to spot a great fish — A veteran’s secrets
Here’s what our veteran diver checks every morning when selecting fish from the tank. Keep these tips in mind next time you visit a sashimi restaurant!
“Clear eyes, strong fins, and a belly that springs right back when you press it. That’s the best fish of the day.”
— Yeonhwa-ri Main Branch Grandmother (51 years of diving)
Check the eyes
A fish’s eyes are like a traffic light for its health. Clear = green light, cloudy = red light!
Check the fins
Fish with lively fins have springy flesh too. Think of it like checking someone’s arm muscles!
Check the color
A healthy fish has vivid coloring, just like how a healthy person has a bright complexion!
Press the belly (experts only!)
A firm belly means fat is well-distributed and the flesh is healthy. Nov–Feb premium fish have incredibly taut bellies!
“In the dead of winter, this fish glistens with oil. Pick it up with chopsticks and it bends ever so slightly under its own weight. Place it on your tongue and it melts away.”
— Yeonhwa-ri Main BranchFlatfish Sashimi 12-Month Seasonal Calendar
This fish is delicious all 12 months of the year! But the flavor profile changes with each season. In the cold months, fat content soars and you get a rich, melt-in-mouth umami. In spring, it’s clean and light. Summer brings a softer, gentler taste. And in autumn, richness slowly builds. No matter when you visit, you’ll experience something unique and wonderful!
Let’s explore each month!
Fat content peaks this month! Each slice practically melts on your tongue with deep, luxurious flavor.
Cold waters keep the flesh firm yet deeply savory. A wonderfully full-bodied experience.
Spring breezes bring a lighter, cleaner taste. Great for those who prefer a delicate bite.
A distinctly refreshing spring flavor! Dip in chojang (vinegar-pepper sauce) for the perfect combo.
The flesh softens, making it perfect for beginners. Try it with a spicy maeuntang (fish stew)!
A lovely smooth texture! Try it grilled or in a maeuntang for a different take on this fish.
Fresh summer ocean flavor. Pairs beautifully with seafood porridge or grilled shellfish.
The flesh starts plumping up again. You can feel the first hints of autumn richness.
Autumn winds bring a growing luster. The lingering aftertaste gets more and more appealing.
Fat is building fast! Nearly as superb as deep winter. A wonderful time to visit.
Cold season begins! Generous flesh delivers a lingering, deeply satisfying flavor.
Perfect for year-end gatherings! The deepest, most indulgent sashimi of the entire year.
Why winter flatfish is the ultimate — The science behind it
Olive flounder are ectothermic (cold-blooded) — meaning their body temperature changes with the surrounding water. Frogs and lizards are ectothermic too! When winter winds blow and water temperatures drop to 8–12°C, the fish stores lots of fat to survive the cold.
That fat is exactly what makes the sashimi so incredibly flavorful! According to NIFS research, fat content from November to February is roughly twice as high as in summer.
On top of that, the smaller fish that flatfish feed on are also fattier in cold months. Better feed means better sashimi — it’s a beautiful cycle of nature!
In summer, the fish spawns and the flesh becomes softer — but that has its own appeal. The tender texture is great for beginners, and if you have it as maeuntang (spicy fish stew) or grilled, the broth from the bones is absolutely wonderful!
The bottom line? This fish is excellent year-round, but November through February is the "golden season" when the rich, luxurious depth of flavor reaches its absolute peak!
Peak fat content! Thick, springy flesh that melts on your tongue with the deepest, most luxurious flavor.
Clean and refreshing flavor. In autumn, oils gradually build, adding more depth with each passing week!
Soft and gentle flavor. Try it grilled, as maeuntang (spicy stew), or with seafood porridge for a different experience!
How to enjoy flatfish sashimi — Each cut tastes different!
Surprisingly, different parts of the same fish taste completely different. It’s like how chicken drumsticks, wings, and breast all have distinct flavors! Knowing each cut makes the sashimi experience twice as enjoyable.
Deungsal (Back meat)
The purest expression of the fish’s flavor. It’s light and not greasy at all, with a subtle sweetness that builds as you chew. If you’re trying sashimi for the first time, start here!
Baesal (Belly meat)
The most popular cut! Rich in fat, it practically dissolves on your tongue. Winter belly meat is absolutely heavenly. Try it with just a tiny sprinkle of sea salt to bring out the natural sweetness!
Engawa (Fin meat)
The prized strip of muscle along the dorsal fin — only a small amount comes from each fish, making it a rare treat! The satisfying chewiness is genuinely addictive. It’s also packed with collagen, which is great for your skin.
Kkorisal (Tail meat)
The tail is the hardest-working part of the fish when it swims, so this muscle is the most developed. That means the best chewing experience! The longer you chew, the more a deep savory flavor unfolds.
“A cold slice of sashimi, then a sizzling bite of grilled shellfish. When these two meet, you\u2019ve found the true taste of Yeonhwa-ri.”
— Yeonhwa-ri Main BranchFlatfish sashimi + Jeonbok-gui (grilled abalone)
Why is this pairing so amazing?
Locals who know their seafood always order grilled shellfish alongside their sashimi. It’s not just because both are tasty — there’s a secret that makes the flavors multiply when you eat them together!

Jeonbok-gui (Grilled abalone)

3 reasons they’re better together
It’s not just because both are delicious. There’s real science behind it!
Cold + Hot
When you alternate between cold sashimi and sizzling grilled shellfish, your taste buds get a pleasant little shock that makes flavors register more intensely. It’s like having ice cream and then a warm drink — both taste even better!
Springy + Chewy
Sashimi is firm and springy; grilled shellfish is tender and bouncy. Two completely different textures that keep every bite interesting. It’s like a texture adventure for your mouth!
Light + Bold
Sashimi is clean and delicate. After a few slices, you crave something richer — that’s when the savory, buttery shellfish delivers perfectly. And after the bold flavor, a fresh slice of sashimi resets your palate beautifully.
🍽️ Try eating in this order!
Start with deungsal (back meat) — The cleanest cut to wake up your palate
Salt-grilled shellfish — A hot, savory bite for a change of pace!
Baesal (belly meat) — Savor the rich, lingering depth of this prized cut
Butter-soy grilled abalone — The nutty butter takes it to another level
Finish with engawa (fin meat) — End on a high note with its addictive chewiness!
Enjoy the freshest sashimi at Yeonhwa-ri Main Branch
Jang-ssi Haenyeo-jip Yeonhwa-ri Main Branch is run by a veteran haenyeo (female diver) grandmother and her son. What sets it apart from other sashimi restaurants is that a professional diver with decades of experience personally manages the live fish tanks!
Every morning, the grandmother inspects each fish one by one. "This one is in great shape today. That one will be better tomorrow." Only the fish in peak condition that day make it onto the serving plate. 51 years of experience gives her an incredibly sharp eye!
When you order, the fish comes straight from the tank and is prepared right away, so freshness goes without saying. The sashimi is served separated by cut, so you can compare the flavors of deungsal (back), baesal (belly), and engawa (fin meat) side by side!
The grilled abalone is also hand-selected by the grandmother. Place it on the charcoal fire, add a pat of butter, and the salty juices from inside the shell meet the butter to create the most incredible aroma!
