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.

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 🥹
