I'd tried Sioldon at another branch, but this was my first time at the Irwon branch. And sure enough, there were lots of students. The surrounding neighborhood is fairly quiet, so it looked like a relaxed place to come for a meal. If you're hunting for a tonkatsu place in Irwon-dong, it's worth a look.

Katsu set menu board at Sioldon Irwon Branch

As a tonkatsu specialist, it has a nice range of menu items. Maybe because so many students come, there's even a good-value ₩11,000 set where you get udon and tonkatsu together. The katsu sets run from the basic sirloin set to the tenderloin set, cheese katsu set, premium sirloin set and mixed katsu set. Beyond katsu sets there's also kimchi katsu nabe (hot pot), katsudon (katsu rice bowl), tomato curry udon and more, so you can choose to suit your taste. Considering today's eating-out prices, I think it's good value.

Rosy pink cross-section of Sioldon tenderloin katsu

What caught my eye first was the rosy pink cross-section of the tenderloin katsu. Isn't that meat color gorgeous? Just looking at it, you can tell how tender it will be.

Crispy fried Sioldon tenderloin katsu

The tenderloin katsu is crispy outside and moist inside, with a great texture when you bite in. The soft, mild flavor that tenderloin is known for really comes through. It wasn't dry at all, and the meat chewed so tenderly that I was happy the whole way through. It looked so good that I kept taking similar photos again and again, haha. The pretty cross-section made me keep picking up the camera.

The salad that came with it has a slightly salty sauce. At tonkatsu places I usually see black sesame or sesame dressing, but Sioldon's sauce was a different style. With the crunchy vegetables, it was nice for cleansing the palate between bites of katsu.

What does the Sioldon cheese katsu set taste like?

The Sioldon cheese katsu set (₩12,900) has cheese inside a crispy coating, a textbook crunchy-outside, moist-inside dish. You know cheese katsu has to be eaten first, before it cools, right? Only when it's warm can you really enjoy that chewy, rich cheese flavor.

Sioldon tenderloin katsu and cheese katsu compared

Can't choose between tenderloin and cheese katsu?

A friend and I went to Sioldon Irwon Branch, ordered one tenderloin katsu set and one cheese katsu set, and split them half and half. This combination was perfect. Personally, tenderloin katsu and cheese katsu have such different charms that picking just one felt like a shame. Tenderloin katsu is great for its soft, mild flavor, while cheese katsu is appealing for its chewy, rich taste.

When the cheese katsu starts to feel a little heavy, a bite of mild tenderloin katsu tastes great again. Alternating between the two flavors meant I never got tired of it and enjoyed it right to the end.
