Ilwon-dong tonkatsu restaurant served with pink salt: Sioldon Ilwon
In short
Sioldon Ilwon Branch is a tonkatsu (pork cutlet) restaurant in the Ilwon-dong restaurant alley near Samsung Seoul Hospital in Gangnam, Seoul. The order was tenderloin cutlet (₩14,900), cheese cutlet (₩12,900) and tomato curry udon (₩9,000), each tasted plain first and then with Himalayan pink salt, mustard and wasabi. Sioldon fries pork aged 72 hours to order, so the cutlets stay moist, and adding the udon makes it a filling one-person meal.

Where is Sioldon Ilwon Branch, and what is the restaurant like?
Sioldon is located in the Ilwon-dong restaurant alley near Samsung Seoul Hospital, so it's really easy to get to!
They also sell tenderloin cutlet, kimchi katsu nabe, and katsudon.
The interior has soft lighting that gives it a warm atmosphere, with tables that seat anywhere from 2 to 4 people~
It's especially set up well for solo dining, so a lot of people were eating privately!

True to being an Ilwon-dong tonkatsu spot, the meat is aging right there 👍


Sioldon fries the cutlets right when you order, using meat aged 72 hours, so the tenderness is on another level!

How to eat Sioldon's cutlets: plain first, then pink salt, mustard and wasabi
There's also a note on how to eat Sioldon deliciously — try it first with no sauce at all, then with Himalayan pink salt, mustard, wasabi, and tonkatsu sauce mixed into mustard, and it's genuinely delicious! They said if you run low on sauce, just ask and they'll give you more~
What we ordered at Sioldon Ilwon Branch

We ordered three things — tenderloin cutlet, cheese cutlet, and tomato curry udon haha
Each dish came out neatly arranged, so it felt like being treated well, and there was plenty of it too~

Tomato curry udon, ₩9,000

The tomato curry udon had a generous amount of sauce, so it looked super delicious even before I tried it ❣️

When you order the udon, a fried tofu (yubu) broth comes alongside it, and being hot, it paired really well!

The noodles were super springy and chewy, and being a curry udon with a subtle tomato flavor, it was delicious~

The sauce was so good I mixed it with rice too, and it really worked well haha Enjoying both the udon and the noodles 🥹


The noodles were also nicely chewy and go perfectly with rice too!

Cheese cutlet, ₩12,900

The cheese cutlet is packed with cheese, so a savory cheese smell wafts out right away!
It comes with wasabi, mustard, and pink salt to pair with it, plus tonkatsu sauce and neatly cut diced radish kimchi.
The cheese cutlet has cheese packed in generously so it stretches and stretches, and the savory flavor is outstanding 💗
It's completely moist, so it's the kind of taste you keep going back for — impossible not to like!


It's also delicious eaten with mustard sauce or tonkatsu sauce like this!!

Tenderloin cutlet, ₩14,900

The tenderloin cutlet was completely moist and melted in my mouth — it was so delicious I was genuinely surprised!

Even the cross-section looked exceptional — this is the textbook definition of crispy outside, tender inside 👍

It's light yet well-seasoned, so you can enjoy it deliciously without dipping it in any other sauce!

Dipping it in wasabi or tonkatsu sauce brings out even more umami, making it even more delicious ^_^
