Craving yellowtail sashimi in Sadang during yellowtail season
It's yellowtail season, so a friend and I went to Susan Sadang Main Branch (수산 사당본점) near Sadang Station for gwangbanbangban (광반방반), a platter that's half flounder and half yellowtail. The weather has turned chilly lately and I was really craving yellowtail sashimi.


We'd gone out to Sadang to hang out and wanted good sashimi with a drink, so we headed to Susan. Since it's yellowtail season, we ordered the gwangbanbangban so we could have flounder and yellowtail together. 🐟



Welcome sake at Susan Sadang Main Branch
The moment we sat down, we were given a glass of sake each. That was the first thing that made me happy. Getting a drink right from the start made it feel like we'd really come for sashimi, and the mood was great.

We clinked glasses, had a light sip, and then started the meal properly. We wanted both flounder and yellowtail, so gwangbanbangban was perfect for us.



What is gwangbanbangban?
Gwangbanbangban is Susan Sadang Main Branch's sashimi dish with flounder and yellowtail served half and half on one plate. It's great when you don't want to settle for just one kind of fish, haha.
We also ordered Su highball (수하이볼) and soju. 🥃 Eating sashimi one piece at a time, drinking and chatting about this and that, the mood was so good. And then, finally, the gwangbanbangban arrived!



Flounder is clean and light, yellowtail is rich and nutty
With flounder and yellowtail split half and half, the plate looked so appetizing. 😍 I tried the flounder first: chewy, light and clean, and really good. Then the yellowtail, and eating it in yellowtail season made it taste even better.
The flounder felt light and the yellowtail felt rich and nutty, so alternating between them never got boring and our chopsticks kept going. It was as good as sashimi from a proper raw fish restaurant, and the two of us kept saying how delicious it was, haha.



Wrapping sashimi in seaweed with dipping oil
The gwangbanbangban at Susan comes with seaweed (gim) and dipping oil (gireumjang), and I really loved this. 🖤 Putting a piece of sashimi on the seaweed and adding a little of the oil was way better than I expected.
We wrapped the flounder in seaweed, then the yellowtail too, and got hooked on the combo, so we kept wrapping every piece, lol. The seaweed adds a nutty flavor, which makes it a great drinking snack. The Su highball went well with the sashimi, and having soju too let each of us drink what we liked.


One plate for two: will there be leftovers?
The two of us finished the whole plate without leaving a single piece. At first I thought there might be a little left over for two people, but that worry was totally unnecessary.
Wrapping sashimi in seaweed kept our chopsticks moving, and between chatting about how good it was, the plate was almost empty before we knew it, haha. In the end we ate every last piece. 😋 Good food really disappears in an instant.
Eating half flounder and half yellowtail meant we got to taste both, which was satisfying, and with the seaweed and dipping oil there were several ways to enjoy it, which made it even better!!
The staff were friendly too, so we had a pleasant time throughout the meal. 😊 The food was good, and the relaxed service made the whole atmosphere feel even better. Eating good sashimi, having a drink and talking to our hearts' content with a friend felt like a properly relaxing time for the first time in a while. Sadang is a great area for meeting friends and hunting for good places to eat, and we had a lovely time there that day.
