Seongsu restaurant for an early 4pm dinner with reservation: Gyuen

When you're on a date in Seongsu, you can't just hop between cafés and bakeries all day — at some point you need a proper Seongsu restaurant for a real meal, haha. We'd done a bakery tour that day and decided to have an early dinner, and it just so happened there was a place with supposedly great gyukatsu (grilled beef cutlet), so we checked it out. This is Gyuen Dang Seongsu Main Branch. :)

I have really good memories of eating gyukatsu on a trip to Japan, so I'd been wanting to try a proper version in Seongsu. We also ordered the hamburg omelet rice alongside it, and the combination of the two turned out better than I expected. I already found myself thinking I'd have to come back next time I'm in Seongsu. :)

Location, reservations, and how far it is from Seongsu Station

The address is 10 Yeonmujang 7-ga-gil, Seongdong-gu, Seoul, on the 2nd floor of the building. The 1st floor has a taco shop called Got It, which is worth noting for first-time visitors. It's about 255m from Seongsu Station Exit 3, roughly a 5-minute walk. Seongsu draws so many people that popular restaurants often have long waits, but this place takes Naver Reservations, so you can lock in a time slot ahead of your visit. :)

An interior that felt like a trip to Japan

We had booked a 4pm slot — since we planned to have the bread from our bakery tour as dessert, we opted for an early dinner rather than a late one. Walking in right on time, the atmosphere was pretty striking. It reminded me of a gyukatsu place I visited in Osaka, and for a moment I felt like I was back in Japan. :)

So before the food even arrived, we ended up talking about our trip for a while. It was also brutally hot outside that day, but the inside was nicely air-conditioned — walking in sweaty from outside into that cool air felt amazing. Our table had a reserved-seating sign on it, and knowing there were seats set aside for people who'd booked ahead made it feel that much more comfortable. :)

Looking at the menu, they had tenderloin and striploin gyukatsu, plus a wide range of side dishes like rice bowls, curry, udon, and omelet rice. After some deliberation we ordered the striploin gyukatsu and the hamburg omelet rice. They also happened to be running a review event, so we decided to write a review afterward and get the okonomiyaki (savory pancake) on the house. :)

Hamburg omelet rice

The first thing that caught my eye when the food arrived was the hamburg omelet rice — it looked a little different from the usual version. A big hamburg (Japanese-style hamburger steak) sat on top of the rice, blanketed by soft, gentle egg. They give you a knife and tell you to slice right through the middle. Once I cut it open, the egg spread softly to either side, like pulling back a blanket. :)

They poured on a generous amount of brown sauce, and just the aroma of it — rich and savory — already got me excited. One bite in, the egg was moist and pillowy, with a soft, melting texture I really liked. Cutting into the hamburg with the knife, it was thick and packed with juice. :)

Taking a bite of the thick-cut hamburg, the meaty flavor really came through. The savory juices paired beautifully with the brown sauce's salty, gently sweet notes. Eating it with the rice made for a very filling meal. The hamburg never felt heavy or greasy, so I enjoyed it thoroughly. :)

Grilling your own striploin gyukatsu

The dish I was most excited about that day — the signature striploin gyukatsu! They set up a small grill with a lit candle, and you grill it yourself at your own pace. The grill gets hotter than you'd expect, so you have to be careful with your hands near it. The gyukatsu was crisp on the outside with a pink center still visible, and just looking at it, the meat seemed incredibly tender. :)

Another thing I really liked here was the Isigny Sainte-Mère gourmet butter. You place the butter on the grill first, then cook the gyukatsu on top of it — the moment the melting butter touched the meat, a rich, nutty aroma burst out. Catching that scent made the slow process of grilling piece by piece feel even more enjoyable. You can pile several slices on at once, but personally, I'd recommend grilling them one at a time. :)

At first I ate it plain, without dipping into anything. The outside was thin and crisp while the inside stayed moist and tender. The distinct savory beef flavor of the striploin came through clearly, and grilling it in butter added an extra nutty finish. Dipped in salt, it was the cleanest way to eat it — you could really taste the meat itself along with the buttery aroma. :)

Salt, fresh wasabi, or the special sauce — which was best?

Adding fresh wasabi brought in that distinctive sharp kick, which nicely cut through any richness. But in the end, I have to admit I dipped it into the special sauce the most... This is the flavor that made me call it a proper Seongsu lunch spot! The special sauce had a salty base with a subtle sweetness and umami that paired really well with the gyukatsu. :)

After every bite I wanted to dip it in the sauce again, so it ended up being the combination I reached for most that day. The striploin was plenty tender already, which made me curious just how tender the tenderloin might be. I'd like to try that next time. :)

Mini okonomiyaki from the review event

I figured the okonomiyaki from the review event, being mini-sized, would just be a token taste, but it was genuinely good. The batter wasn't thick or dense — it was moist and soft instead. Cutting a bite with the knife, it broke apart softly, letting the sauce and toppings come through together. It's the kind of flavor that keeps you going back for another bite. :)

Visiting at 4pm meant we could eat at a relaxed pace and leave without rushing. If you'd rather take your time over a meal than just eat fast and go, this Seongsu restaurant suits that pace well. We went with the striploin gyukatsu this time, and honestly, my satisfaction level was pretty high — the special sauce was that good. :)

Operating hours and break time

Next time I'd like to try the tenderloin and add on the fried squid legs (geso age) too. To wrap up, here are Gyuen Dang Seongsu Main Branch's operating hours: weekdays from 11:30am to 10pm, with break time from 3pm to 5pm and last order at 9pm. On weekends, it's open from 11:30am to 10pm with no break time — worth keeping in mind when planning your visit. :)
