Katsumonster Yeonsinnae is a Japanese tonkatsu restaurant a three-minute walk from Yeonsinnae Station Exit 5. It serves triple katsu, which lets you try several cuts at once, alongside cold noodle dishes, with salt, wasabi and tonkatsu sauce to change the pairing. The one-person set comes as a mixed katsu with cold udon, and the two-person set includes katsu with udon or cold momil. The loin is rich in juices, the tenderloin is soft, and the mozzarella cheese katsu stretches long when bitten.
