Solo tonkatsu after bowling in Yeonnam-dong: Katsu Monster Yeonnam Main Branch (카츠몬스터 연남본점)

This morning I went bowling with my brother. He headed off to work and I was left on my own, and suddenly I really wanted Japanese food. Maybe it was the exercise, but I didn't want anything light. I wanted a proper, filling meal, haha.

I like mixing wasabi into katsu sauce. The kick of the wasabi cuts the richness just right, haha. With several sauces on the table, dipping each piece in something different seemed like fun too.

How is the triple katsu? Loin, fillet and cheese on one plate

The triple katsu (₩21,000) at Katsu Monster Yeonnam Main Branch puts three kinds of katsu on one plate: loin, fillet and cheese. With so many options I got stuck deciding, then figured it was perfect for a solo meal and ordered it.

The crispy fried katsu looked really appetizing from the first glance.

Eat the cheese katsu first, while it's hot

Cheese katsu has to be eaten while hot, so I ate it first. Seeing the cheese stretch, I want it again even now while writing this post, haha. I guess this is why people order cheese katsu. The cheese hardens quickly as it cools, so I recommend eating it right when it arrives.

My favorite: the juicy pork loin katsu

The loin and fillet katsu were good too, but the loin katsu was especially my taste. It was juicy and practically melted in my mouth, so I kept reaching for more.

Since I was eating alone, I even filmed a video like a mukbang YouTuber, and it was more fun than I expected, haha.
