Cheonan sushi restaurant lunch stop en route to Seoul: Ganghan Sushi

What kind of sushi restaurant is Ganghan Sushi Cheonan Buldang Branch?

Ganghan Sushi is a Buldang-dong favorite known for delicious sushi made with fresh salmon, flounder and tuna sourced every dawn, carefully aged, and paired with shari made from top-grade Saecheongmu rice.

They only use Saecheongmu rice milled within the last two weeks, so the grains don't fall apart easily and keep good bounce — meaning the shari, the very essence of sushi, actually tastes great. Through a low-temperature aging technique that brings out deeper flavor than live fish, each type of fish goes through its own optimal aging time, giving you chewier, more umami-rich sushi. That's apparently the secret behind this Buldang-dong favorite.

The owner puts cleanliness and hygiene first, running an open kitchen so the whole cooking process is transparent, and following a rule that all ingredients are used up the same day — which made it reassuring to enjoy the sushi. The clean, comfortable space and service also made it perfect for eating solo.

What to order on a lunch stop to Seoul: the omakase sushi set

Ganghan Sushi Cheonan Buldang Branch is a Cheonan Buldang-dong favorite where you can enjoy delicious aged-fish sushi in various set configurations to suit your taste, plus handmade tonkatsu, salmon bomb rice bowl, and freshwater eel rice bowl at great value.

On the way to Seoul I was debating what to eat and landed on the omakase sushi — and both the quality and the composition were hugely satisfying for the price.

• Superior raw salmon sushi, top-grade salmon aged in the Osaka style to cut fishiness and boost flavor
• Tuna sushi made with extra-large honmaguro belly, deep and rich in flavor
• Extra-large flounder sushi from Wando, aged 24 hours for the best flavor

Fish cake udon, seafood cutlet and cabbage salad come with the set

Before the sushi arrives, fish cake udon, seafood cutlet, cabbage salad and soybean soup come out as standard — great for a hearty solo lunch.

What is in the 12-piece omakase sushi set for 23,000 won?

A great-value way to try a variety of sushi — the 12-piece omakase sushi for ₩23,000. This is Ganghan Sushi's omakase set, made with top-grade ingredients like flounder, salmon, tuna, sweet shrimp, monkfish liver, abalone and eel.

An extra-large 3kg flounder from Wando, aged 24 hours, made for standout, chewier flounder sushi at this Buldang-dong favorite. The nicely aged flounder sashimi was cut thick enough that both texture and taste were perfect — the Wando flounder sushi.

Top-grade 7kg salmon aged in the Osaka style to cut fishiness and boost that savory flavor — the superior raw salmon sushi. Topped with raw onion and a special sauce, which also cut any richness, balancing everything nicely.

Tuna sushi made with belly from an extra-large 200kg honmaguro, deep and rich in flavor — the color looked truly vivid and fresh. The honmaguro belly and swordfish belly melted in my mouth. Getting to enjoy this at this price felt lucky.

Made with three whole premium amaebi sweet shrimp, this sweet shrimp sushi let me really taste that rich, sweet flavor — standout at this Buldang-dong favorite.

A very rich abalone liver sauce with steamed abalone sushi — this one was incredible too. The chewy abalone paired with the rich liver sauce was the kicker.

They serve washed aged kimchi alongside, which cuts through any richness.

Monkfish liver gunkan, steamed abalone and beef tartare gamtae sushi

Monkfish liver — sometimes called sea foie gras — piled generously onto a gunkan roll. Loaded on without holding back, the ankimo filled my mouth and made me happy.

The combo of rich abalone soy sauce and chewy abalone was incredible.

A la carte add-ons: honmaguro tuna sushi and egg sushi

I additionally ordered tuna sushi, plus Japanese-style egg sushi made with domestic eggs aged in mirin for sweetness. Being able to add these à la carte was a nice touch — overall, far more satisfying than a cheap conveyor-belt sushi place. A solid Buldang-dong, Cheonan favorite.
