Suyeong sashimi restaurant near Gwangalli: wild rock bream platter

It was the second night of our Busan trip. The night before, we'd eaten all sorts of seafood at a dachi (raw seafood pub), so this time I wanted to focus purely on sashimi, no other food. While looking for a wild sashimi restaurant near Gwangalli, I found this place — Sintongyeong Gul Gukbap!

Going by the name alone, you'd think it's just a gul gukbap (oyster soup) place, but they actually sell everything from wild sashimi to seasonal seafood. Our wild assorted sashimi platter came generously loaded with rock bream, flounder, and marbled flounder. The long-sliced cuts had a texture unlike anything else, and I got curious about the other menu items — this became a Suyeong spot I want to revisit.

Gwangalli to Sintongyeong Gul Gukbap: 10 minutes by taxi

Sintongyeong Gul Gukbap was about a 10-minute taxi ride from Gwangalli Beach. It's tucked inside the Suyeong-dong food alley, a good spot for dinner or drinks. It wasn't hard to get there by public transit or taxi from Gwangalli, so it was easy to fit into our Busan trip.

Out front, there was a tank full of seafood. Even the outdoor tank water was clear and well-kept, which got my hopes up for the sashimi quality before we even walked in. At any seafood place, I always end up checking how the tanks are maintained, and overall the impression here was clean.

Inside Sintongyeong Gul Gukbap: a local Suyeong crowd

Walking inside, the tables were already packed with customers. Unlike the mostly tourist-filled restaurants around Gwangalli, most of the customers here looked like Busan locals. Groups were gathered eating sashimi and seafood over drinks — it really felt like Busan.

The menu reads like a sashimi restaurant, not a soup shop

Even though the name says gul gukbap, the actual menu was closer to a sashimi restaurant that also serves seafood, not a typical soup place. There were seasonal offerings like shrimp, gizzard shad, and octopus, plus a variety of drinking-snack dishes. Since we wanted to focus on wild sashimi that night, we ordered the small wild assorted sashimi platter for ₩60,000 — the small size seemed plenty for two.

Ten side dishes before the sashimi arrives

Since we were in Busan, we ordered Daesun, the local soju. Right on cue, staff running a Daesun promotion came by and handed out hangover-relief drinks to everyone. Totally unexpected timing, but hey, score 🤭 — it let us drink a little more freely that evening.

While our drinks were being prepared, the banchan (side dishes) were set out one by one. It was a mix of dishes you'd typically see at a sashimi restaurant along with a few that felt more like soup-shop side dishes. With so much variety, it was great to pick at before the sashimi even arrived.

Cucumber and carrot, boiled sweet potato and seasoned mideodeok (sea pineapple), baek-kimchi and seaweed stem, sautéed mushrooms and salad, seasoned pickled radish and acorn jelly, even silkworm pupae — the spread was generous. Boiled sweet potato at a sashimi restaurant was a first for me, oddly enough, but I kept reaching for it anyway.

The most memorable banchan was the seasoned mideodeok. I usually like mideodeok, but I'd only ever had it in seafood stew or steamed dishes — here it came seasoned like a tangy pickle. The crunchy pop of texture paired with the tangy seasoning really hit the spot. It was also great for cleansing the palate between bites of sashimi, and I ended up nearly finishing the whole bowl.

What comes on the 60,000 won wild sashimi platter

While we were still working through the banchan, the wild assorted sashimi we'd been waiting for arrived. The large plate was packed tightly with sashimi — a generous portion even for the small size. The glistening slices looked fresh just from a glance.

What stood out was how the sashimi was sliced. Instead of the usual wide, short cuts, each piece was sliced into a long, slender shape. I've heard that thickness and slicing direction change the texture and flavor of sashimi, and this clearly wasn't cut carelessly — it had the feel of a technique and pride specific to this restaurant.

That day's wild assorted sashimi lineup, from left to right, was rock bream, flounder, and marbled flounder. It leaned heavily toward white-fleshed fish, but each species had a different chewiness and nuttiness, which made comparing them as we ate part of the fun. The lineup would probably change depending on the season or what came in that day.

What surprised me most was the rock bream. Not only was I glad to see rock bream included in the wild assorted platter, but there was a real, generous amount of it — not just a taste. Rock bream isn't something you get to eat easily, so I felt good about our order.

Marbled flounder: firm and clean-tasting

I started with the marbled flounder. I'd also had marbled flounder the night before at a dachi in Gwangalli, but the wild version had a totally different texture from the first bite. The flesh had structure without being tough, and a clean sweetness came through as I chewed. I was struck by how different the same fish can taste depending on the thickness of the cut and its freshness.

Flounder: bone-in sekoshi-style crunch

Next was the flounder. It was prepared sekkochi-style, sliced with the small bones still in. At first I worried the bones might be bothersome, but they weren't harsh or uncomfortable at all. If anything, the crunchy texture added to the nutty flavor and made it more appealing.

Rock bream: sweetness that builds as you chew

Now it was time for the rock bream I'd been most looking forward to. The marbled flounder and flounder were both delicious, but the rock bream looked firm and glossy even before tasting it.

To taste the rock bream on its own, I dipped one piece lightly in soy sauce. The first thing I noticed was the springy texture, followed by a nutty flavor and sweetness that built as I chewed. I finally understood why people seek out rock bream and pay a premium for it.

Perilla wraps, aged kimchi and chili-vinegar sauce: how to eat it

I tried the marbled flounder wrapped in perilla leaves too. Strong perilla flavor can overpower sashimi, but the flounder's thick, good texture held its own even wrapped. Adding a bit of garlic and ssamjang made it work well as a drinking snack too.

Next I topped a piece of sashimi with aged kimchi. The tangy flavor and crunchy texture of the kimchi paired well with the clean white fish. After alternating between soy sauce and chili sauce, it was a nice way to switch things up mid-meal.

I dipped the nutty flounder in chili sauce too. The sweet-tangy sauce softened the texture of the small bones and made the flounder's nuttiness come through even more richly. Personally, I thought flounder paired better with chili sauce than soy sauce.

Finally, I wrapped some rock bream in perilla leaves too. It felt slightly wasteful eating rock bream as a wrap, but the generous portion made that indulgence possible. Whether eaten plain, with soy sauce, with aged kimchi, or in a perilla wrap, the rock bream's signature springiness and nuttiness came through clearly every time.

Is Sintongyeong Gul Gukbap worth the trip from Gwangalli?

If you only judged Sintongyeong Gul Gukbap by its name, you might walk right past it without realizing it sells wild sashimi. But once I actually ate here, the texture and flavor of the long-sliced wild sashimi left a real impression — a Suyeong sashimi restaurant worth remembering.

The marbled flounder was firm and clean, the flounder was crunchy and nutty, and the rock bream delivered real, building sweetness with every chew. Even the small assorted platter came with a generous amount of rock bream, giving the two of us plenty of ways to enjoy it. The banchan lineup was extensive too, and the tangy mideodeok in particular is a flavor I keep thinking back on.

This time we focused on the wild assorted sashimi platter, but now I'm curious about the other menu items too, like shrimp, gizzard shad, and octopus. If you're looking for a sashimi restaurant near Gwangalli or a Suyeong-dong spot with real local atmosphere, I'd recommend this place. I'd love to come back on my next Busan trip and try whatever good seasonal sashimi and seafood is on offer that day.
