How does the cheese katsu taste at Sioldon Irwon Branch?

Cheese katsu and mini soba served together

Soon the cheese katsu and mini soba I ordered arrived. A lovely smell reached my nose and I couldn't wait to dig in.

Cheese katsu at Sioldon Irwon Branch
Cheese katsu generously filled with cheese

The cheese katsu here is packed with cheese, so if you like cheese, you can't help but enjoy it. When the cheese stretches, you can see how generous the amount is and how warmly it's melted.

Dipping the cheese katsu in sauce
Cross-section of crispy, juicy tonkatsu

Dip it in the sauce that comes with it and you get tonkatsu that's crispy outside and full of juice inside. The pork is well brined, so the seasoning is good and the meat is tender.

Putting a little of the wasabi that comes alongside on top is a great treat too. Good fried food is fine with just a dip in salt, and Sioldon's batter was exactly like that. The little dish that holds the sauce is so cute that it's a photo-worthy sight.

Sauce-dressed vegetables served with the tonkatsu

Side vegetables and a generous bowl of rice

Vegetables come with the meal by default, so eating them between bites keeps your mouth fresh and the meal light. The sauce drizzled over the vegetables was tasty too, so I kept eating them.

Generous bowl of rice served with the cheese katsu

The rice that comes with it is really generous. With tonkatsu you often wish there were more rice, but you don't have to worry about that at Sioldon.

Mini cold soba ordered as a side

What's the mini cold soba side like?

The cold soba (buckwheat noodles) I ordered as a side is perfect for hot weather like we've been having. There's ice slush in the broth, so it's even more refreshing.

Lifting up the cold soba noodles

The noodles were good and the broth had soaked in well, so it was a satisfying side.
