I used to think frying pork was just... frying pork, but now I get why the flavor feels so much more refined — it's thanks to the chefs' effort. You can also see menu items like tenderloin katsu, kimchi nabe, and katsu-don in photos. ![Sioldon tenderloin katsu and kimchi nabe menu introduction](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-04-i7r9k-966.webp) ![Sioldon katsu-don and other menu introduction image](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-05-z6lz7-966.webp) ## Where is Sioldon Ilwon Branch? Location, parking and solo seats It's located near Samsung Seoul Hospital, and parking is available right in front of the restaurant 👍🏻 The place was clean too!! There are separate window seats for solo diners, which was great, and the sofa seats were super comfortable~! We look after our own guests! Disposable aprons are provided too, so you can eat without worrying about your clothes 🥢 ![Sioldon Ilwon Branch table with disposable aprons](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-06-kh8q2-966.webp) During lunch and dinner peak hours there tends to be a lot of waiting, so order first as soon as you arrive, then write your name on the waitlist⛤ ## Sioldon menu and prices: which set is the best value? ![Sioldon value set menu board](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-07-1a7lx-966.webp) Sioldon's value set It's already on the kiosk, but I think they wrote it separately for reference! But I was too distracted by the cheese katsu to notice..🫠 I'll try the set next time!! The curry udon also seems like it might be something special..! ![Sioldon Ilwon Branch tonkatsu menu board](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-08-gfdfp-966.webp) ![Sioldon Ilwon Branch rice bowl menu board](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-09-1rhzc-966.webp) ![Sioldon Ilwon Branch udon and buckwheat noodle menu board](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-10-1pqic-966.webp) ![Sioldon Ilwon Branch country-of-origin labeling board](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-11-nwztd-966.webp) The country-of-origin labeling is clearly displayed, and the menu is neatly divided into tonkatsu, rice bowls, udon, and buckwheat noodles. Prices range from ₩8,000 and up! You can also add tenderloin katsu, cheese katsu, and more separately, so it might be nice to order a main and try several sides. ![Guide to enjoying Sioldon tonkatsu display](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-12-fd4en-966.webp) ## How to eat Sioldon tonkatsu: salt, sauce and order of bites - Enjoy it plain, with no sauce at all - Sprinkle on some Himalayan pink salt - Add a touch of wasabi or wholegrain mustard - Mix mustard into the tonkatsu sauce and dip ![Sioldon Ilwon Branch Naver receipt review event notice](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-13-iu43d-966.webp) You get a free drink if you take part in the Naver receipt review event, so make sure to join in 💕 ![Sioldon Ilwon Branch mixed katsu set table setting](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-14-m8z9m-966.webp) ## Mixed katsu set with sirloin and tenderloin, 15,900 won Mixed katsu (sirloin, tenderloin) set, ₩15,900 — the first dish we ordered. I was torn between sirloin and tenderloin, so I just ordered the mixed set! When it first arrived it looked kind of cute and modest, but it turned out thick and packed with actual meat rather than just batter, so it was really filling! It comes with cute diced radish kimchi, sauce, rice, and fried tofu soup — and the soup broth is seriously..👍🏻 ![Rice and fried tofu soup served with the mixed katsu set](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-15-8735e-966.webp) Sioldon, a favorite near Samsung Seoul Hospital, says they tested various pork breeds and use the tastiest ones — Dodram Hanpork and Seonjin Pork Hanpork! For brining, instead of regular salt they use nuruk salt (fermented rice salt) to boost the savory flavor. A chef who cares even about the salt — so sweet~! ![Cross-section of Sioldon sirloin katsu and tenderloin katsu](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-16-oga1p-966.webp) Doesn't the tenderloin and sirloin just look juicy even from the photo?🥹 They said they worked hard using their own developed batter to get that crispy-outside, juicy-inside texture, and honestly the coating felt different. The moment I took a bite, I thought, ah, this place is really something. ![Thin, crispy coating of Sioldon tonkatsu](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-17-1ghgk-966.webp) A meticulous Sioldon, careful even about the length of the breadcrumbs The coating is thin but somehow holds the meat firmly together while staying perfectly crispy — the texture was really special! Makes you wonder if the cross-aging is what creates this texture!? ![Close-up of a piece of Sioldon sirloin katsu](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-18-6b2ju-966.webp) ![Close-up of a piece of Sioldon tenderloin katsu](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-19-r740t-966.webp) The sirloin was delicious, and the tenderloin was delicious too — it's fried in oil, so how is it this light and clean? It's a specialness you can only understand by trying it yourself. ![Sioldon Ilwon Branch cheese katsu set, ₩12,900, table setting](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-20-6rji2-1200.webp) ## Cheese katsu set, 12,900 won: cheese that never hardens Cheese katsu set, ₩12,900. What came out was a truly cheese-packed cheese tonkatsu! First of all, the cabbage salad dressing was totally my type 🔫 ![Cabbage salad served with the cheese katsu set](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-21-1sepy-966.webp) ![Sioldon fried tofu soup full of tofu](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-22-z171e-966.webp) The soup broth is amazing 👍🏻 It's full of fried tofu too, so the texture was great, and the rice was fluffy and nice. You can easily finish a whole bowl~! With most cheese katsu, the cheese usually hardens fast as you eat, but at Sioldon Ilwon Branch the cheese in the cheese katsu doesn't harden! It stays chewy and stretches all the way to the last bite, which makes eating it fun. It has a soft chewiness that pairs really well with the meat — the best cheese katsu I've had recently. ![Sioldon cheese katsu with cheese stretching out](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-23-1yusi-966.webp) ![A piece of cheese katsu dipped in sauce](https://img.superchart.com/images/siholdon-ilwon-mixed-cheese-katsu/siholdon-ilwon-mixed-cheese-katsu-24-gt23j-966.webp) Dab it in sauce, cheese stretching out~🤎 They seem to work hard to keep the oil clean too, since everything tasted really clean! Anyway, the sirloin and tenderloin — totally recommended!!!! I'm planning to come back this weekend to try other menu items.
