Triple katsu for ₩21,000. I found Katsu Monster Yeonnam Main Branch while looking for somewhere to eat alone in Yeonnam-dong 🍚 There are so many good restaurants in Yeonnam-dong that it's honestly hard to decide what to eat. That day I suddenly craved crispy tonkatsu, so I searched for a katsu place and ended up here! I especially like trying a little of several kinds rather than sticking to one menu, so the moment I saw it on the menu, the triple katsu caught my eye 👀 ![A plate of triple katsu with three kinds of tonkatsu](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-02-1p139-900.webp) Looking at it again, my mouth is watering!!!! ㅋ_ㅋ ![Cross-section of cheese katsu with stretchy cheese](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-03-19v7z-900.webp) The cheese was insane!!!! ![Interior of Katsu Monster Yeonnam Main Branch](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-04-1xq20-900.webp) ## Katsu Monster Yeonnam Main Branch: a Yeonnam-dong tonkatsu spot built for solo diners Katsu Monster Yeonnam Main Branch had a vibe that made eating alone feel totally comfortable.

The price is ₩21,000! You get to try cheese katsu + tenderloin katsu + loin katsu all in one dish, so it seemed like a pretty solid solo meal option. But honestly, the portion is way too much — even for a big eater like me... I got so full that I had to pack up the rest to go. ![A full spread of triple katsu with rice and side dishes](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-11-1mjav-900.webp) The cheese katsu was so good ㅠㅁㅠ If I'd only eaten one kind of tonkatsu, I would've felt like I was missing out, but getting to try all three at once made it really satisfying. And it looked so appetizing from the start 🤍 With crispy-fried tonkatsu served alongside rice and side dishes, it was a pretty filling meal overall! ![Close-up of crispy-fried loin katsu](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-12-14h9z-900.webp) ![Cross-section of a thick piece of tonkatsu](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-13-1wqdf-900.webp) ### Loin katsu: the basics done right Such a violently good-looking tonkatsu ㅠㅠ Crispy on the outside and melted right in my mouth 🥩 You can't talk about tonkatsu without mentioning the loin. The batter was crisped just right and let the meat's flavor really come through — I enjoyed it a lot. If the cheese katsu was savory and soft, the loin felt a bit more like classic tonkatsu. Eating all three together, I never got tired of it and kept reaching for more. ![A plate with wasabi, salt, and pepper](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-14-125z5-900.webp) ![A piece of tonkatsu dipped in salt](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-15-1m3q3-900.webp) The wasabi + salt + pepper combo was also great ![A piece of tonkatsu picked up with chopsticks](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-16-jhb7u-900.webp) ![Cross-section showing crispy batter and juicy meat](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-17-9e5y4-900.webp) More than anything, tonkatsu is all about the crispiness of the batter and the juiciness of the meat. It tasted even better than I expected, so I ate it feeling genuinely satisfied. ![A piece of light, clean-tasting tenderloin katsu](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-18-mak0b-900.webp) ### Tenderloin katsu: the lean, clean-tasting cut 🤍 And personally, the tenderloin is the cut I always want to try when I eat tonkatsu. It's lighter and softer than the loin, so the balance between the batter and the meat was really nice. Getting to try several kinds at once, I went cheese katsu → tenderloin → loin in order and had fun noticing the differences in flavor between each. ![Eating the triple katsu in the order of cheese, tenderloin, and loin katsu](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-19-ixfc3-900.webp) ## Is Katsu Monster worth it for a solo meal in Yeonnam-dong? 🫶🏻 Personally, I was pretty satisfied with the triple katsu this time. Above all, I loved being able to try cheese katsu, tenderloin katsu, and loin katsu all in one order. For someone like me who has trouble picking just one, a menu like this is such a welcome option ㅋㅋㅋ At ₩21,000, it's a menu worth considering when you want a proper tonkatsu meal in Yeonnam-dong. ![The triple katsu plate after finishing the meal](https://img.superchart.com/images/yeonnam-katsu-monster-triple-katsu-solo/yeonnam-katsu-monster-triple-katsu-solo-20-sqqt0-900.webp) And since it's not awkward to eat here alone, it should work well for anyone looking for a solo dining spot in Yeonnam-dong! If you want delicious tonkatsu in Yeonnam-dong, or you have trouble choosing between cheese katsu, tenderloin, and loin, try the triple katsu and have all three like I did 😆🥢 I really enjoyed it that day, so next time I go to Yeonnam-dong I want to try some other menu items too!
