Seongnam sashimi restaurant for dinner with parents: Haeseon

So good... Are you really going to spend a million won at a flashy izakaya, struggling through the Japanese menu? Or just...

Go for Haeseon’s ₩40,000-per-person course near Sunae Station in Bundang. It beats most seafood buffets and easily puts that bargain-basement izakaya vibe in its place.

Top-grade live fish, aged and sold out the very same day. If you do not get there quickly, you may wait and still miss it. Haeseon is the reliable sashimi spot by Sunae Station.

There really is nowhere else like this... A ₩40,000 aged sashimi course. Protect this value at all costs.

For ₩40,000, you get a beautifully arranged plate of sea bream, flounder, and rockfish (+ engawa, the fatty fin meat). Then there is chopped live octopus with beef tartare, sea bream spicy fish stew, fried shrimp, fries, corn cheese, sea squirt, and grilled sea bream head. How can it be this luxurious—and this filling? No need for a course that arrives in ten separate plates. They bring out only the good stuff.

Haeseon’s aged sashimi is live fish aged at a low temperature of 0–5°C on the day. During aging, natural flavor compounds develop, maximizing the fish’s own savoriness and aroma.

I am not even a live-fish-sashimi person, you know. Sashimi should be aged. Sweet, with that lovely cling-to-your-tongue texture.

Finding Haeseon near Sunae Station and its hours

Less than a five-minute walk from Sunae Station, right behind Gratea Officetel.

It is open Monday through Saturday, 16:00–22:00. Sunae Station has loads of office buildings, so go while the former Lotte Department Store site is still vacant. A company is planned for that spot—do you really think you will be able to visit Haeseon as freely once that happens?

There is a fish tank outside and a standing sign explaining the course. It is on the first floor and extremely easy to find.

How the aged sashimi course begins

Fresh seafood and aged sashimi whose color is on another level.

It starts with soft vegetable porridge and jang-guk, a savory Korean soup. The soup tastes like it uses crab or shrimp as its base, too.

As you eat the sea-scented sea squirt appetizer and talk about what to eat tomorrow...

It arrives.

Wait! I need to get a proper overhead shot. A commanding platter of aged sashimi set on ceramic. The slices are thick, and the color is gorgeous. If I were an uncle, I would order a drink.

The sweetness and texture of same-day aged live-fish sashimi

Let me spotlight every cross-section. Because the fish is delivered live that day and then aged, each slice maximizes its umami, subtle sweetness, and tongue-clinging texture.

And two pieces of engawa. Without this, can you really say you ate rockfish?!

The course dishes that follow the sashimi

The guaranteed pleasure of a full course.

The sashimi alone is worth it, but...

That day’s course included corn cheese, grilled sea bream head, and beef tartare with octopus. The bubbling oil on the just-grilled sea bream head is so tempting... Light and crisp in texture, with a rich sea bream flavor.

The freshness is exceptional—the octopus is still moving energetically. The beef tartare is well seasoned. This second main brings together sesame oil, sweetness, and the refreshing tang of pear.

The fried shrimp is coated in coconut, too: big, springy, and an unusual flavor.

A hearty finish with sea bream head spicy fish stew

It would be a shame to finish without maeuntang, spicy fish stew.

Maeuntang bubbling away in a ttukbaegi (Korean earthenware pot) with bean sprouts. With sea bream head in it, the broth is clean and endlessly spoonable. Koreans really do find peace only when there is soup, honestly.

Every course dish is neat, clean, and of course freshly cooked. It is not a huge restaurant, but once dinner starts, it fills up; the wait continues, then it ends with ingredients sold out.

This is a great place in Bundang to take your parents for a meal. It is clean without being intimidatingly formal. Like my father, they may say, “Hey, this is way better than most buffets.” Each dish is high quality. It is also popular for office dinners among Sunae Station workers, and the staff are kind.

After you finish, head out to Tancheon Stream and walk off the meal. Confirmed, guaranteed, certain—there is no way this is not delicious. Haeseon, an excellent restaurant specializing in aged sashimi courses by Sunae Station.
