It's Kosi Konkuk University Branch (코시 건대), known for neat set meals and crispy fried dishes! I'll go through the cozy atmosphere and honest reviews of what we ordered.

How was the mixed katsu set at Kosi?

Without hesitation, our first main order that day was the mixed katsu set. It arrived neatly arranged on a big tray, and the bright, golden-brown coating, fried in clean oil, was impressive right away.

The mild, tender tenderloin and the chewy, rich loin were a perfect pair, and I could tell right away why this place has a reputation as a Konkuk Univ. tonkatsu spot. The broth that comes with the set was clean yet deeply savory, and with the firm noodles it showed why this is a good udon place near Konkuk Univ. too.

Is the lotus root tempura side worth ordering?

Our special side with the mixed katsu set was lotus root tempura (연근 덴뿌라), the very essence of crispiness. Inside the thin, crunchy batter, the lotus root's signature crisp texture was fully intact, and it worked as a great accent between bites of the meal. It wasn't greasy, just lightly fried, so the root's gentle sweetness and nutty flavor stood out, and a light dip in the tentsuyu (tempura dipping sauce) made the fried flavor even better.

How to enjoy katsu more: fresh wasabi and salt

The hearty meatiness of the mixed katsu and the light crunch of the lotus root tempura went together so well that I never got tired of it, right to the last piece. The warmth of freshly fried katsu, cooked to order, and the filling set meal recharged me in the middle of a busy day. Besides the regular sauce, a little fresh wasabi and salt boosts the natural flavor of the meat, so you can enjoy it to the last bite.
