While we waited for our order, the savory smell of the breading sizzling in the open kitchen drifted softly through the restaurant, and my mouth was watering the whole time.

That day we ordered the two basics of Katsu Kim's tonkatsu, hire katsu (fillet) and rosu katsu (loin), one each, and shared them.

Hire katsu (fillet): thick but tender, not dry

The fillet katsu is really thick, yet not dry at all, and so tender it almost melts in your mouth. The second I took a bite, my husband and I locked eyes like, "This fillet is insane," haha.

The breading is super crisp, and every bite releases juicy, moist meat. It's good with a pinch of salt and a dab of wasabi, and dipped in the sauce that comes with it the savory flavor just explodes. I finished every last piece.

If you like the light, tender texture fillet is known for, I'd definitely recommend the hire katsu.

Rosu katsu (loin): savory fat and a satisfying chew

The loin katsu has firm-textured meat with a nicely savory layer of fat mixed in, so the chew really comes through. Loin has a clearly different charm from fillet!

The fat was especially chewy, and my husband ended up eating mine too, haha. The breading is fried crisp without feeling greasy, and it stayed clean and never went soggy to the end.

What comes with Katsu Kim's tonkatsu

The tonkatsu comes with a cabbage salad generously topped with dressing, plus a soup (jangguk). The sides were quite neat: the crunchy cabbage cut the richness of the fried food, and the warm, rich soup was just right to sip between bites.

Thick cuts of meat, plenty of juice and crisp breading: Katsu Kim sticks to the tonkatsu basics, and we left satisfied with clean plates. The fillet's tenderness and the loin's savory chew were both great, so if you're two people, I recommend ordering one of each and sharing.
