I ordered the tenderloin cutlet, and the meat was so fluffy-soft it practically melted—so happy! Now, let me start my story of eating alone in Ilwon-dong! ![Photo showing the location of Sioldon Ilwon Branch](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-02-1ojgu-700.webp) ## Location and parking at Sioldon Ilwon Branch The address is 12 Ilwon-ro 9-gil, Gangnam-gu, Seoul, South Korea, on the first floor. It is located right opposite Samsung Medical Center. From Irwon Station, it takes about 13 minutes on foot. Hours are daily from 11:00 to 20:30.

There were five four-person tables and four two-person tables, plus two bar seats looking out the window. ![Photo of window bar seats and high-back chairs](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-04-fun4r-700.webp) The chairs had high backs, making it easy to focus comfortably on conversation. I went for a solo meal before dinner, but customers kept coming in. ![Photo explaining how to write down a waiting number](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-05-1h14k-700.webp) Seeing the sheet for writing down your place in line, I could tell it was already a well-known Ilwon-dong restaurant. How thoughtful of them to provide hair ties and disposable mouthwash too! ![Photo of the receipt event notice](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-06-14ku6-700.webp) They were running a receipt event. Write a review including tags such as Samsung Medical Center, Ilwon-dong, and tonkatsu, and you get a free can of soda! ![Photo of Sioldon’s tonkatsu menu](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-07-10we5-700.webp) ## Tonkatsu and udon menu Here is the menu at Sioldon, a popular tonkatsu spot in Ilwon-dong. The loin cutlet set is ₩12,900, the cheese cutlet set is ₩12,900, the tenderloin cutlet set is ₩14,900, kimchi cheese nabé is ₩13,900, and tomato curry udon is ₩9,000. ![Photo of tonkatsu set-menu prices](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-08-1vbb0-700.webp) Tonkatsu was the main attraction, with udon, memil (buckwheat noodles), and curry available as sides. ![Photo of tonkatsu and udon set menus](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-09-5yg30-700.webp) At Sioldon, a popular Ilwon-dong restaurant, the ₩11,000 value set lets you choose cold memil, spicy Cheongyang chili, or tomato curry udon, along with tenderloin or cheese. Takeout gets a ₩2,000 discount. After thinking and thinking for ages, I ordered the tenderloin cutlet set with an added mini fried-tofu udon, extra cheese cutlet, and a drink. So excited for the tonkatsu~ While waiting, I looked around the restaurant. The pork, cabbage, radish, and rice were all domestic. A poster on the wall also said that Sioldon cooks to order rather than preparing food in advance, and that its premium tonkatsu is aged for 72 hours, so my anticipation went way, way up. ![Photo of a poster explaining that food is cooked to order](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-10-1kp1q-700.webp) The water was buckwheat tea, so it had a lovely nutty flavor. ![Photo of nutty buckwheat tea](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-11-hgehv-700.webp) ## Thick and tender tenderloin cutlet After a short wait, Sioldon’s tenderloin cutlet arrived. ![Photo of a full Sioldon tenderloin cutlet meal](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-12-8ebe8-700.webp) The tenderloin tonkatsu was thick, and there was a generous mound of salad and rice. It was fun to have so many sauces too: wasabi, Himalayan pink salt, tonkatsu sauce, whole-grain mustard, and more. ![Photo of assorted sauces for tenderloin cutlet](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-13-1876p-700.webp) First, I took a big bite of loin. The breading was wonderfully crisp, while the tenderloin inside broke down softly, and that contrast in texture was so fun. ![Photo of crispy breading and tenderloin cutlet](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-14-rh1ep-700.webp) ![Photo of the soft interior of a tenderloin cutlet](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-15-3k9kn-700.webp) Sioldon is a great tonkatsu place by Samsung Medical Center. Dipping it into Himalayan pink salt really brought the seasoning of the tender lean meat to life. ![Photo of tenderloin cutlet with pink salt](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-16-gwmfu-700.webp) ## Springy mini fried-tofu udon and cheese cutlet The udon had plenty of scallions, fried tofu, and noodles. When I slurped up a bite, the noodles were so springy. ![Photo of mini udon with scallions and fried tofu](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-17-opllu-700.webp) ![Photo of udon in bonito-flake broth](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-18-11g5n-700.webp) The deep bonito-flake broth was incredible. I totally approve of this Samsung Medical Center restaurant! ![Photo introducing the cheese cutlet](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-19-1fiyn-700.webp) The cheese cutlet was packed with cheese, too. ![Photo of cheese cutlet packed with cheese](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-20-13pao-700.webp) The warm cheese stretched and stretched, with a rich, nutty flavor. ![Photo of warm, stretchy cheese cutlet](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-21-17p9x-700.webp) ![Photo of rich cheese cutlet](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-22-rfabh-700.webp) Even the side dishes were delicious here. ![Photo of side dishes served with tonkatsu](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-23-pdpbb-700.webp) I finished with a cider and felt like I was about to burst. ![Photo of a meal finished with cider](https://img.superchart.com/images/irwon-dong-siol-don-pork-cutlet/irwon-dong-siol-don-pork-cutlet-24-rltg5-1200.webp) ## Tonkatsu recommendation near Samsung Medical Center Sioldon is an impressive Ilwon-dong restaurant because its tenderloin is so soft. It is right opposite Samsung Medical Center, and although the parking is tight, there is space for up to two cars, making it a perfect restaurant if you have errands nearby. The Japanese-style tenderloin cutlet is crispy outside and tender inside, so I strongly recommend Sioldon Ilwon Branch. ## Where it is - Sioldon Ilwon Branch (시올돈 일원점) (시올돈 일원점) - 12 Ilwon-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/@porcelain-rice/irwon-dong-siol-don-pork-cutlet/ · https://superchart.com/llms.txt
