Seongsu Japanese izakaya: moriawase for two with smoked sashimi, Oukan

In short

Oukan is a Japanese-style izakaya on Yeonmujang-gil in Seongdong, Seoul, near Seongsu Station. Craving aged sashimi, the writer started with Oukan's complimentary crackers and a beer, then ordered the moriawase for two (an assorted aged sashimi platter) and named the smoked sashimi, with its smoky aroma like a fine whisky, as the best of the platter. With a satisfying atmosphere and aged sashimi, Oukan is a strong pick for a Seongsu date or a second round of drinks.

Main photo from a visit to Oukan, an izakaya near Seongsu Station

I was looking for an izakaya (Japanese-style pub) in Seongsu with a good mood, and that's how I ended up at Oukan! This time I went because I was craving aged sashimi. The atmosphere was lovely, and above all the sashimi was really delicious, so I left very satisfied.

If you're looking for a date spot in Seongsu or an izakaya with a great mood, listen up! Today I'm sharing my experience with the Moriawase for two at Oukan, which I tried myself.

What kind of place is Oukan, the Seongsu izakaya?

Oukan is an izakaya on Yeonmujang-gil in Seongsu where you can enjoy a Japanese-style atmosphere together with tasty aged sashimi. Seongsu has so many good restaurants and bars, but Oukan was a place that lets you have both aged sashimi and a good mood.

It seemed like a good place for a date on a special day, or for a drink with a friend when you want a nice atmosphere.

I liked the cozy, stylish feel the moment I walked in. Rather than a rowdy pub, it suited a day when you want to enjoy food and conversation a bit more calmly.

Soft lighting and interior at Oukan

Thanks to the soft lighting and stylish interior, Oukan feels like a small izakaya in Japan. It wasn't just the food; the atmosphere of the place was impressive too.

Seongsu's signature hip vibe blends well with the Japanese izakaya feel, which made it even more charming. The mood is great for a date with a partner, and also good for chatting with friends over tasty food! If you're looking for a blind-date spot or an anniversary date spot in Seongsu, it's worth putting on your list.

At Oukan, once you order, they first bring crackers as a free starter :) Crackers with a beer is the best, isn't it? Haha.

What's in Oukan's Moriawase for two?

After much agonizing, what I ordered at Oukan was the Moriawase for two. Moriawase is a Japanese-style sashimi platter with several kinds of fish arranged on one plate.

I was looking forward to it because Oukan lets you try a wide variety of aged sashimi. With the different kinds of fish, the colors were vivid and the plating was pretty, so it caught my eye the moment it arrived.

It was a set that's nice to taste slowly, one piece at a time. If you love sashimi, you'll definitely be happy to see a platter like this.

How did Oukan's aged sashimi taste?

The aged sashimi in Oukan's Moriawase had a great texture and savory depth, so I kept reaching for more. After all, even in a place with a great mood, the taste of the food matters, right? Oukan isn't just about atmosphere; the sashimi was satisfying too!

Maybe because it's aged, the flavor in the mouth was great too, and it was fun to savor it one piece at a time. Alternating between the different kinds of sashimi let me notice the differences in texture and taste, which I liked. If you like fresh sashimi, an aged sashimi menu like this will feel even more appealing.

Above all, the sashimi was really delicious that day, so my satisfaction was high. Getting tasty aged sashimi in a place with a good mood, it went well with a drink too. If you're looking for a great aged sashimi spot in Seongsu, I'd recommend Oukan's Moriawase!

The best of the Moriawase: smoked sashimi

If I had to pick just one thing from Oukan's Moriawase, it's the smoked sashimi. There are so many kinds of aged sashimi, but if I had to choose one, it's this one!!! The smoked sashimi!!! The moment it goes in your mouth, a smoky aroma spreads, and it feels like sipping a fine whisky, haha. My eyes went wide for a second, it was such an irresistible taste. I really, truly recommend it.

Is Oukan good as a second round in Seongsu?

Oukan was a good place to spend relaxed time over tasty aged sashimi. It would work as a second round after a meal in Seongsu, or from the start when you want to spend time with good snacks.

Because the mood is so good, it's a place that comes to mind when you want something a little different. That day I ordered the Moriawase for two, and the sashimi was really good and I liked the atmosphere too, so I left in a great mood.

The sashimi was so good that this place stayed in my memory. Next time I look for a nice place in Seongsu, I think Oukan will come to mind again! I recommend it if you want a good time with tasty aged sashimi.
