## In short

Katsu Monster Yeonnam Main Branch is a tonkatsu restaurant on Dongyo-ro 38-gil in Yeonnam-dong, Seoul. On a day off, the writer arrived with her boyfriend just before the weekday lunch rush and ordered loin katsu and cheese katsu for ₩31,000 total, splitting both half and half to compare the lean, savory loin katsu with the rich cheese katsu. She preferred the cheese katsu, and the thick miso soup with pieces of meat in it was a standout too.

## Katsu Monster before the weekday lunch rush: can you eat alone here?

Yeonnam-dong is always packed, so I deliberately went before the lunch rush on a weekday. The place had a clean yet comfortable atmosphere, great for a relaxed meal. It had that casual Yeonnam-dong feel — good for going with a friend, or for a low-pressure date where you just want good food ✨

The vibe seemed fine for solo dining too, so it looked like a place you could easily drop into on a day you just want tonkatsu by yourself. While we were eating, quite a few people came in alone. It also seemed to be popular for delivery — delivery riders kept coming in and out.

## What's on the menu at Katsu Monster Yeonnam

![Menu board listing Katsu Monster's tonkatsu types](https://img.superchart.com/images/katsu-monster-yeonnam-weekday-lunch-cheese-katsu/katsu-monster-yeonnam-weekday-lunch-cheese-katsu-05-1kima-900.webp)

Katsu Monster had a wide variety of tonkatsu (pork cutlet) types. The main ones are loin katsu, fillet katsu, premium loin katsu, cheese katsu, assorted katsu, mix katsu and triple katsu, and besides tonkatsu there's also a good range of noodle dishes like memil (buckwheat noodles) and udon. If you feel like one tonkatsu alone isn't quite enough, it might be nice for two people to order a katsu plus a noodle dish to share.

The cold memil noodles look like they'd be amazing in summer. Slurping down a cool bowl of broth like that sounds so good...

![Menu guide describing loin katsu and fillet katsu](https://img.superchart.com/images/katsu-monster-yeonnam-weekday-lunch-cheese-katsu/katsu-monster-yeonnam-weekday-lunch-cheese-katsu-07-1fue5-900.webp)

Each type of tonkatsu — loin katsu, fillet katsu, and so on — comes with an explanation, so you can just order according to your taste.

## Our order for two at Katsu Monster: ₩31,000 total

We ordered loin katsu and cheese katsu, for a total of ₩31,000. That felt like just the right price for a Yeonnam-dong lunch. Tonkatsu is also a dish almost nobody dislikes, so it seems like a good pick to bring coworkers or friends along too.

## What the cheese katsu tastes like

First up, the cheese katsu I ordered. If you're a cheese lover, this dish will win you over just from the look of it. There's cheese packed in between the meat inside the tonkatsu. The savory cheese, crispy coating, and juicy meat all came together really well — total textbook crispy-outside, tender-inside. But I figured eating only cheese katsu might get heavy after a while, so my boyfriend and I split it in half and mixed the two.

## Loin katsu at Katsu Monster and the best sauce pairings

![Thick-cut loin katsu from Katsu Monster](https://img.superchart.com/images/katsu-monster-yeonnam-weekday-lunch-cheese-katsu/katsu-monster-yeonnam-weekday-lunch-cheese-katsu-10-3xoth-900.webp)

Next, the loin katsu 🐷 The thick-cut tonkatsu looked delicious just from the visual. The outside was fried crispy, and the meat inside had a mix of lean and fatty parts, so the texture was great from the first bite. It had that satisfying chewy tonkatsu feel — light yet savory. If you want to really taste tonkatsu itself, the loin katsu is the reliable, well-rounded choice.

There's tonkatsu sauce, salt, wasabi, and various other condiments to pair however you like. I dipped mine in tonkatsu sauce with a huge amount of wasabi mixed in, and the wasabi cut through the richness of the fatty meat so well — so tasty. If you want to taste the meat's natural flavor, salt with just a bit of wasabi is nice too.

And there was salad dressing ready for the cabbage salad, so I drizzled it on and mixed it all up. The cabbage was super crunchy and fresh. With rice, meat, and cabbage all together, it felt like you were getting carbs, protein, and fat in one meal.

## Loin katsu vs cheese katsu: which one was better?

The cheese katsu was seriously so good. If loin katsu is the light, clean-tasting option, cheese katsu is the one that hits you with strong savoriness and cheese flavor. Personally, I liked the cheese katsu better.

It also came with soup, and while other tonkatsu places usually give you a bland miso soup, this one had a richer, saltier flavor — more like a proper doenjang stew. I actually liked that better. It also had meat in it, which made it taste even better.

So happy I got to visit a great tonkatsu spot in Yeonnam-dong on my precious day off 🩷

If you're looking for a good tonkatsu restaurant in Yeonnam-dong, Katsu Monster Yeonnam is worth a stop. If you like thick, crispy tonkatsu, I'd recommend starting with the loin katsu, and if you love cheese, definitely try the cheese katsu too ‼️
