Freshly fried tonkatsu is THIS good!? 🥹 If you want both tenderloin and cheese, go for the mixed katsu B 😉💗
Don't you ever just suddenly, desperately crave tonkatsu (pork cutlet)? That was exactly my mood that day lol.

I wanted a crispy-coated, juicy-inside tonkatsu so badly that I went looking, and the place I found and visited was Katsu Monster Gangdong Office Branch :)

Katsu Monster Gangdong Office Branch is an easy walk from Gangdong Office Station, so it's not a hassle even if you're coming by public transit…!
The store actually sits right across from the Gangdong-gu Office, so it's a great stop if you have plans near the district office or are looking for somewhere to eat in Seongnae-dong 👍🏻

And since Olympic Park is nearby too, it works well as a date course that flows into a walk afterward 🌿 Perfect when you're not quite ready to head straight home — a walk to help digest, and that's a wrap!


An open kitchen where you can watch the frying
Katsu Monster Gangdong Office Branch has an open kitchen, so if you sit at your table you can watch the tonkatsu being prepared and fried right in front of you! 🤤


Personally, I love places with a full view into the kitchen like this haha. Being able to watch your order come together right in front of your eyes somehow makes you look forward to it even more~~?! 👀✨



After some menu agonizing, mixed katsu B: tenderloin + cheese
Katsu Monster has quite a lineup — from a basic set to mixed katsu, cheese katsu, udon, cold soba, and more~!?

After going back and forth, what I ended up ordering this time was the mixed katsu B — the tenderloin + cheese combo!

Because I wanted the tenderloin AND the cheese 😋 If you make me pick just one, that's way too hard… so in the end, I'm the type of person who just gets both lol = me lol lol
Barley tea, plus rice and soup refills
And the moment I sat down, one thing quietly caught my eye~!~~! 👀 Instead of plain water, they had nutty, toasty barley tea ready! I'm the type who gets weirdly fond of a place over small details like this lol, and a cup of barley tea really got my appetite going 💖

Before the tonkatsu even arrives — the sauce comes out first 🤤
Then rice and soup followed too. They said if you run out, you can just ask for more! Amazing ㅠㅠㅠㅠ what an event ㅠㅠㅠㅠㅠ🥹💗


How does the freshly fried mixed katsu B taste?
🐷 The freshly fried tonkatsu arrives!! 🐽 The cutlets that had been busily frying away in the open kitchen finally showed up 🙌🏻


I'd been eagerly waiting, and the moment the hot, freshly fried tonkatsu landed on the plate, it already looked delicious just from the visuals 🥹💗


Have to take photos, have to eat — the busiest person in this situation = me lol lol 📸
I quickly snapped some photos and then grabbed a piece right away! With the crispy coating meeting the warm cutlet inside, tonkatsu really has to be eaten the moment it comes out 😋

What I especially loved about the mixed katsu B I ordered is that being tenderloin + cheese, you get to enjoy the mild, tender tenderloin katsu alongside the nutty, stretchy cheese katsu, all on one plate 🧀💗


Dip the hot, freshly fried tonkatsu into the sauce, add a spoonful of rice… honestly, that combo is impossible to resist 🤤

Why it worked for both solo dining and a date
🥹 Ate well and got nice and full 💗 Before I knew it, the plate was completely cleared lol. So many satisfying points at Katsu Monster Gangdong Office Branch 🍽️

A great spot for a light solo meal, and just as good for a delicious tonkatsu outing with friends or a partner! 👍🏻 (I'm quietly putting it on my revisit list since I want to try the other katsu menu items next time haha.) A solid recommendation if you're looking for good food near Gangdong Office Station 👍🏻 Ate something delicious today, and came home with my mood just as full as my stomach~~😋💗
