Daecheong Station tonkatsu at weekend opening: yubu udon set, Sioldon

In short

Sioldon Irwon Branch is a premium tonkatsu (pork cutlet) restaurant in Irwon-dong, Gangnam, Seoul, near Daecheong Station and Samsung Seoul Hospital. The writer arrived for weekend dinner right as the break time ended and ordered a sirloin katsu set with mini yubu udon (udon with fried tofu pouches) instead of soup, plus a cheese katsu set with long, stretchy cheese. The cutlets were crisp outside and juicy inside, and Sioldon Irwon Branch earned a full recommendation for meat quality, flavor and value.

We ate in the restaurant and chose two sets: the sirloin katsu set (with mini yubu udon) and the cheese katsu set. The nabe (Japanese-style hot pot) looked delicious too. Next time I have to try the nabe!

Guide to enjoying Sioldon tonkatsu

How to eat Sioldon tonkatsu: pink salt, wasabi and sauces

First enjoy the tonkatsu plain, with no sauce, to taste the pork itself. Then add a little Himalayan pink salt, fresh wasabi or whole-grain mustard. Dipping it in tonkatsu sauce mixed with Japanese mustard is also heavenly! When you finish, return your dishes to the return station.

How was the sirloin katsu set with mini yubu udon?

Wow, just look at the quality of this meat. It looks amazing. As in the tips above, I first enjoyed the tonkatsu plain with no sauce, then dipped it in Himalayan pink salt.

The pink salt was seriously so good! A little fresh wasabi or whole-grain mustard on top, or dipping in tonkatsu sauce with Japanese mustard, is just insanely tasty~ The portion is generous too, so we were nicely full.

Swapping the soup for mini yubu udon

Normally Sioldon's basic katsu set comes with tonkatsu, rice, soup and assorted sauces, but I chose the mini yubu udon (udon with fried tofu pouch), so I got udon instead of soup. It's called mini udon, but the portion was pretty big?!

Hot broth and springy noodles, such delicious udon that it made me happy.

Stretchy cheese in Sioldon's cheese katsu

Does the cheese in Sioldon's cheese katsu set really stretch?

The cheese tonkatsu set! Wow, the amount of cheese is truly enormous. Look at how it stretches! Other cheese tonkatsu don't stretch this far, but that's Sioldon for you~ Sioldon is Sioldon.

The cheese is so soft and rich, absolutely delicious. And it's not just the cheese, the meat is amazing too!
