You order at a kiosk, and once you sit down they bring the food to your seat, haha. ![Kiosk menu at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-09-6oxpa-900.webp) ![Menu information at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-10-kbexh-900.webp) ## How was the special sirloin katsu at Sioldon? This time I ordered the special sirloin katsu (特等심카츠) and the cheese katsu! The special sirloin katsu passed the test on looks alone. ![Special sirloin katsu set at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-11-2fvsm-900.webp) The thick-cut cutlet is really crispy outside and moist inside, and true to the special sirloin cut, it was juicy, with a rich meaty flavor the more I chewed. ![Thick-cut special sirloin katsu](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-12-1eq6m-900.webp) ![Cross-section of juicy special sirloin katsu](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-13-1tg8n-900.webp) ![Close-up of special sirloin katsu](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-14-1s5z1-900.webp) The breading isn't too thick either, so I could really taste the meat, and it never felt greasy, so I enjoyed it to the last bite. ![A piece of special sirloin katsu with thin breading](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-15-89vfv-900.webp) ![Special sirloin katsu dipped in salt](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-16-ivm3v-900.webp) The special sirloin katsu with just a light dip in salt brings out the true flavor of the meat, and personally that was my favorite way to eat it. ## Is the cheese katsu at Sioldon too rich? The cheese katsu at Sioldon Irwon Branch doesn't have too much cheese, so it balances well with the meat. If you like cheese, I think you'll be really happy with it. The moment you cut it in half the cheese stretches out, and it looks so appetizing. Nutty cheese with crispy tonkatsu is a combination that never fails. ![Cheese katsu at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-17-6dba8-900.webp) It's not the overly cheesy, heavy kind; it balances well with the meat, so I enjoyed it down to the last piece. ![A piece of cheese katsu](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-18-13wfm-900.webp) The side dishes and sauces served alongside are neatly presented and go well with the tonkatsu, which made the meal even more satisfying. ![Side dishes and sauces served with the tonkatsu](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-19-1v388-900.webp) ![Full tonkatsu spread at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-20-14umb-900.webp) ## Is the ₩3,000 curry add-on at Sioldon Irwon Branch worth it? The kicker at Sioldon Irwon Branch is the curry!!!! I added curry for ₩3,000, and the curry is honestly a total rice thief 🥹 All the way through I kept thinking, "I get why this place is popular." I was curious about the curry too, so I added it for ₩3,000, and I was really glad I did. It isn't the usual side curry; it's good enough to order on its own, haha. ![Curry added for ₩3,000 at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-21-1xk2t-900.webp) Mixing it into the rice 😭😭😭😭 ugh, I want to eat it again. It has a deep, rich flavor with real savory depth, so it's great with rice, and dunking the crispy tonkatsu in it was the absolute best combo. The nutty tonkatsu and the rich curry go so well together, which made it an even more satisfying meal. Next time I visit, I'll definitely add the curry again!!!!!! ![Tonkatsu and rice with curry](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-22-pwhv0-900.webp) ![Tonkatsu dipped in curry](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-23-40nno-900.webp) ## Is Sioldon Irwon Branch worth going back to? If you're looking for a place to eat near Samsung Seoul Hospital, or want good tonkatsu in Irwon-dong, I really recommend Sioldon Irwon Branch. ![Closing photo of the meal at Sioldon Irwon Branch](https://img.superchart.com/images/ildong-sioldon-tonkatsu-curry-addon/ildong-sioldon-tonkatsu-curry-addon-24-4if8b-900.webp) There are so many tonkatsu hotspots these days, but it's been a while since I was happy with everything: the quality of the meat, the crispiness of the breading, and the clean atmosphere. Next time I really want to try the mixed katsu set (모듬카츠정식) and the kimchi cheese nabe (kimchi cheese hot pot) that many people recommend. Taste, atmosphere and cleanliness all satisfied me at Sioldon Irwon Branch! If you like tonkatsu, I hope you'll visit at least once. ## Where it is - Sioldon Irwon Branch (시올돈 일원점) - 12 Irwon-ro 9-gil, Gangnam-gu, Seoul, South Korea - 서울특별시 강남구 일원로9길 12 1층 - 37.489524, 127.0826117 - Google Maps: https://www.google.com/maps/search/%EC%8B%9C%EC%98%AC%EB%8F%88%20%EC%9D%BC%EC%9B%90%EC%A0%90/@37.489524,127.0826117,17z --- Superchart · https://superchart.com/en/@suwon-thin-mirror/ildong-sioldon-tonkatsu-curry-addon/ · https://superchart.com/llms.txt
