Ilwon-dong tonkatsu restaurant with kiosk ordering: Sioldon Ilwon
In short
Sioldon Ilwon Branch is a Japanese tonkatsu restaurant in Ilwon-dong, Gangnam, Seoul, near Samsung Seoul Hospital. Stopping by on the way to a Gachon University festival, the writer used the kiosk to order kimchi nabe with an extra tenderloin katsu and a Pepsi Zero Sugar Lime, eating the bubbling earthenware-pot broth alongside two thick pieces of tenderloin cutlet. The sharp, spicy kimchi nabe and the tender katsu made Sioldon Ilwon an easy choice for anything from a solo meal to a family dinner.

Outside Sioldon Ilwon: a warm, polished Japanese tonkatsu shop
The exterior of Sioldon Ilwon Branch pairs a clean white base with tidy wood-framed details, giving off a warm impression at first glance.
Soft orange point lights above the signage light up the front of the store warmly day or night, and the full glass front lets you feel the cozy interior atmosphere from outside.
A standing sign and posters of the main menu are neatly arranged near the entrance, making it easy for first-time visitors to spot the signature dishes.
Inside Sioldon Ilwon: seating and atmosphere
Stepping inside Sioldon Ilwon Branch, warm wood tones blend with cream-ivory walls throughout, giving a very comfortable and hygienic feel.
Seating: alongside the plush, comfortable sofa-style table seats, there's also a bar table by the window, making the layout work well for groups of 2–4 as well as solo diners.
Lighting and open kitchen: designer pendant lights hang from the ceiling for a cozy dining mood, and an open kitchen off to one side, kept spotless, adds to the trust in hygiene.
Friendly signage: notes posted around the walls read things like "Rice completes the tonkatsu!", "Pink doesn't mean undercooked (a note on the pinkish phenomenon)," and "Cooking starts as soon as you order and takes about 15 minutes" — small touches that show real pride in the food and care for customers.
Tasting the food: spicy broth and juicy cutlets
This time at Sioldon Ilwon Branch I ordered kimchi nabe, an extra piece of sirloin katsu (hire katsu), and a refreshing Pepsi Zero Sugar Lime to finish things off. Everything — the earthenware pot, rice, soup, sauce, and side dishes — arrives neatly arranged on a single tray.
① Kimchi nabe (kimchi katsu nabe, a katsu hot pot)
The kimchi nabe, bubbling hot in the earthenware pot, comes topped generously with savory beaten egg, melty cheese, and chopped scallions over a rich, concentrated broth — visually appetite-stirring right away.
The spicy, deeply savory kimchi broth soaks all the way into the katsu's crust and meat. Thanks to the earthenware pot, the dish stays warm until the very last bite — a great touch.
② Tenderloin katsu, ordered as an extra piece
Two round, thick pieces of sirloin katsu, holding pale pink juices, arrive on their own small plate. Just looking at the cross-section you can see the meat grain intact and the juices soaked through moist and full.
Take a bite and the outer crust is thin and crisp, while the sirloin meat inside is so tender your teeth leave a soft impression the moment you bite in. The more you chew, the more the clean, rich meaty aroma fills your mouth. Dip it in the house tonkatsu sauce with a bit of mustard mixed in, or try it with salt or wasabi, to bring out the sirloin's natural savoriness even more.
③ Rice, clear soup and side dishes
Warm, glossy white rice and a hearty soup loaded with fried tofu pouches come as standard sides. The rice's nutty flavor pairs perfectly with the soup and the tonkatsu. The clean fizz of the Pepsi Zero Lime balances beautifully against the heavy katsu and the spicy nabe, rounding things off perfectly.
