Mapo Japanese restaurant for kimchi katsu nabe: Katsu Monster

In short

Katsu Monster Yeonnam Main Branch is a Japanese cutlet restaurant in Mapo, Seoul, between Hongdae and Yeonnam-dong. I tried the 16,000 won kimchi katsu nabe and gabrisal sang loin cutlet as full set meals; the light breading and spicy nabe stood out. A filling pick for a Hongdae date.

There are all kinds of tonkatsu (Japanese breaded pork cutlet), including tenderloin, loin, gabrisal, and cheese varieties, plus cold buckwheat noodles and cold udon that are great for a refreshing summer meal. On slightly chilly days, you can also enjoy spicy fish-cake udon, bonito fish-cake udon, the spicy kimchi katsu nabe, tonkatsu curry rice bowls, and udon ✨

A very Japanese-feeling space and tablet ordering

The interior was full of Japanese vibes too, so it felt a little like traveling in Japan 👍🏻 That glimpse of the fan decoration is such a nice touch〰️

Kimchi katsu nabe and gabrisal sang loin katsu

I ordered the kimchi katsu nabe, and my boyfriend ordered the sang loin katsu〰️ The sang loin katsu is a gabrisal pork cutlet, said to have a richer aroma and flavor 🔥 It was described as a dish full of juices with a deep, nutty richness 👍🏻 The kimchi katsu nabe lets you enjoy spicy kimchi and katsu together ✨

Ordered kimchi katsu nabe and sang loin katsu

The kimchi katsu nabe looked spicy just from looking at it, alongside the big, hearty-looking sang loin katsu—✨ Everything we ordered had arrived〰️ Each dish came as a full set meal 🔥

The sang loin katsu came with rice, soup, cabbage salad, kimchi, and dessert, while the kimchi katsu nabe came as a full set without soup〰️ Tonkatsu sauce, cabbage-salad dressing, wasabi, and salt were stocked at every table, so we could add as much as we wanted 👍🏻

Tonkatsu sauces and accompaniments

The cabbage salad came with a light dressing, which was great for cutting through any richness that built up while eating the tonkatsu 👍🏻

Light sang loin katsu and spicy kimchi nabe

Since the sang loin katsu uses gabrisal, a fatty cut, I wondered if it might be too rich ❓ But it was lighter than I expected, and I loved its tender texture 👍🏻 Above all, the breading was thin rather than heavy, which made it so delicious ✨

Spicy kimchi katsu nabe

The kimchi katsu nabe was spicy and pleasantly sharp, with savory katsu in the kimchi nabe, so it was delicious without feeling rich 👍🏻 It is a flavor Koreans would definitely love 🔥 I recommend Katsu Monster Yeonnam Main Branch to anyone looking for tonkatsu on a Hongdae date ✨
