Salmon steak gnocchi at Omil Seongsu, a Seongsu-dong brunch spot

Today I went on a date in Seongsu-dong and stopped by Omil Seongsu, a place that's been going viral for its visuals. It's delicious and cute at the same time, so it's a great spot for a proper little healing session. Let's get into the honest review.

Where is Omil Seongsu and what are its hours?

Omil Seongsu is on the 1st floor of 37-1 Achasan-ro 5-gil, Seongdong-gu, Seoul. It's about an 8-minute walk from Exit 1 of Seongsu Station.

Hours are 11:30-21:15, last order 20:30. *Closed on September 25, 2026 for Chuseok.

Is there parking at Omil Seongsu?

Omil Seongsu doesn't have its own parking lot, so you'll need to use a nearby public parking lot. There's one right next door, the Seongsu 2-ga 3-dong public lot, but it's often full, so I'd recommend public transit instead. Parking is really tough on weekends, and on weekdays spots open up a bit after the lunch rush.

Inside Omil Seongsu: a look around

The moment you turn into the alley, there's a facade full of atmosphere. Red brick vibes, perfect. This alley has that old-school Seongsu feel, so it's great for photos.

How long is the wait, and can you book?

Omil Seongsu takes waitlist entries through CatchTable. I visited on a weekday at 2pm and had no wait, but if you come during weekday lunch hours expect 20-30 minutes, and up to an hour on weekends — so I'd recommend joining the waitlist and going around the Seongsu pop-ups in the meantime, haha. Reservations are possible through Naver and CatchTable.

Stepping inside, it's a completely different mood from outside. Warm-toned lighting is on, making it feel cozy. The tables aren't spaced super wide apart, but it's not cramped either — fine for a date or eating with a kid. The window seats have big windows that bring in the alley atmosphere too, great for a couple's brunch.

The inner seats look a bit cozier. I noticed families with kids heading there. Maybe because of the cute menu, it's popular with families. Even I, an adult child, got excited 😁

Self-bar and house-made pickles

The self-bar. Water isn't set on the table by default, so if you need water, you scoop it yourself at the self-bar. Wet wipes and napkins are ready too, and there are homemade pickles that are genuinely delicious. I normally don't even eat pickles with pizza, but at Omil I do 😁

The restroom is indoors too. Even the restroom vibe is good, ugh. They even have mouthwash ready — the owner's sense of detail is amazing. You can rinse your mouth before you head out.

Pineapple ade, 6,900 won

Pineapple Ade, ₩6,900. The first drink to arrive, and Omil Seongsu's pineapple ade is genuinely delicious. It's the drink I always order here. Just the right amount of carbonation, sweet and refreshing. It comes in a glass that looks like it's from SpongeBob's house, which adds extra cuteness.

Rubber duck omurice, 16,900 won

Rubber Duck Omurice, ₩16,900. Ahh, so cute. This isn't my first visit but the cuteness gets me every time, haha. The highlight is the quail eggs shaped like a duck's face. They also give you a rubber duck as a little souvenir, and since it's summer, it's even wearing a tube float. Small, precious duck~ The baby at the next table eyed my duck, but my inner introvert couldn't speak up, so... I couldn't give it away. This one's mine now, adult child privilege 😎

A shame to break it apart, but I was hungry so I dug in anyway 😆 The egg is so soft the spoon just slides right in. The flavor is mild, not too strong, so it's great for kids too. As the adult child that I am, it was even better with the sauce.

Thick yet tender egg, and cute quail eggs. I want that egg blanket again...

Little rubber duck friends?! Come on into my mouth.

What does the salmon steak gnocchi (19,900 won) taste like?

Salmon Steak Gnocchi, ₩19,900. I was torn between pasta and gnocchi — Omil Seongsu's pasta was genuinely delicious last time, but I hadn't tried the gnocchi yet, so this time I went for it.

They told me to mash the salmon and mix it with the sauce, but I wanted to try it plain first, so I took one bite of just the salmon. It's more of a crispy-outside style than a moist one, cooked a bit more through.

The gnocchi, wow. That chewiness no Korean can resist. It's a shame the photos don't fully capture how chewy it is.

Now, following the staff's instructions, I mashed the salmon and mixed it all together. It's a really thick, rich style. This is my first time trying this combination with salmon, and since the sauce has a slight kick of spice, eating it with the salmon makes it savory and just a touch spicy — the combination is really good. If there's one thing I wished for, it'd be a bit more sauce. It's just that good 😁

Is Omil Seongsu worth a visit?

The alley where Omil Seongsu sits definitely has fewer people than the area around Exits 3 and 4 of Seongsu Station, so you get a quieter, more relaxed meal — this was a visit to Omil in Seongsu-dong that was a treat for both the eyes and the mouth thanks to the cute visuals. Overall the flavors are mild and not too strong, so I'd recommend it to anyone looking for a restaurant to visit with kids, or for a cozy date spot.
