Konkuk Univ. katsu and udon shop: a first-timer's cold udon set, Kosi
In short
Kosi Konkuk University Branch is a Japanese restaurant specializing in house-made udon and tonkatsu, on Achasan-ro near Konkuk Univ. Station in Gwangjin, Seoul. A regular took a sibling there for the first time, ordering loin katsu with an extra side katsu for themselves and recommending the cold udon set, which comes with tempura and inari sushi (fried tofu pouch rice), to the sibling, who loved both the noodles and the katsu. The verdict at Kosi: add a side katsu when you order udon, and make your katsu a set so you get udon too.

What is Kosi Konkuk University Branch like, and can you park?
Kosi Konkuk University Branch is a tonkatsu (pork cutlet) specialist and house-made udon shop on Achasan-ro near Konkuk Univ. Station. You can fit about two cars in front of the shop, and there's a dedicated parking lot behind the building. If you're hunting for great tonkatsu and udon near Konkuk Univ., this is the place, the one I keep going back to!
It's good for family meals with kids and for group dinners, because it's a Geondae Station-area restaurant where you can actually park~ Parking-friendly restaurants around here are hard to find, right? But Kosi has parking!

There's room for about two cars in front of the shop, and the dedicated lot is behind the building.
Why did Kosi's tonkatsu and udon make me a regular?
Every friend of mine who loves tonkatsu agrees this place is the real deal, and the udon noodles are made in-house too. When people on TV travel to Japan and introduce great katsu and udon, I'm not jealous at all, and the reason is that I know Kosi.
My family has a history of actually bringing in Osaka udon, so I'm a little picky about udon... but Kosi? Well, ^^


I always tell people looking for a house-made udon shop to stop by Kosi~ After a proper bowl of udon, the udon you used to eat at highway rest stops goes right back on the shelf.
Kosi's opening hours and how to avoid the wait
Kosi opens at 11:10, has a break from 15:00 to 17:00, and closes at 20:30. There's a wait at mealtimes, so you need to move a bit early to get in right away.
We went in and found our seats. It's a place where you do the opening rush ^^ Or you can go for a slightly late lunch. Whenever I visit, the kitchen and the dining hall are always busy, yet both are always clean.

Loin katsu with side katsu, and cold udon set for my sibling
This day at Kosi, I ordered the loin katsu plus an extra side katsu, and recommended the cold udon set to my younger sibling who came with me. Once again I brought along someone who didn't know Kosi yet.


I had udon last time, so this time it's back to the loin katsu! It's really good, you know ^^

For my companion I recommended the cold udon. Order it as a set and tempura comes along too, so you get a nicely laid-out full meal. Any menu item at Kosi can be made a set, so keep that in mind!

Want katsu with your udon? Add it as a side
I always thought it'd be nice to add tonkatsu to udon... and at Kosi you can add katsu as a side ^^ I really wanted my sibling, who was going for udon, to taste Kosi's katsu too. Everyone I've brought here so far has been satisfied and become a regular, so I figured this time would work too.
The cold udon set comes with tempura and one extra inari sushi, so it's filling, which is great! With the weather getting hotter, some of you may be craving cold soba... come to Kosi and try the cold udon~

If you visit Kosi, the house-made udon shop near Geondae Station with springy, bouncy noodles, you'll get really great udon.


When you have udon, definitely add the katsu too~ You might regret skipping it ^^ Udon means adding katsu, and when you eat katsu, order it as a set and have the udon along with it~

Kosi's tonkatsu is the real thing, so I even tell friends who only hunt for katsu spots to go. The cheese katsu is good, and the loin and tenderloin katsu are all good too. It's a proper tonkatsu specialist!


How do you eat Kosi's cold udon?
For Kosi's cold udon, just dip the noodles in the sauce for a moderate amount, then lift them out and eat.


You really have to try Kosi's noodles yourself~ They're on a different level from ordinary udon shops. My sibling said they were delicious too~ I feel proud every time I introduce a good restaurant!


Kosi's loin katsu with sauce, salt and wasabi
Kosi's loin katsu can be eaten alternating between tonkatsu sauce, salt and wasabi. Pick up a nicely fried piece, dip it in the sauce, and into the mouth it goes~
I recommended my sibling try a piece too... and they were happy with it~ Eat this and you're always satisfied!


You can put wasabi on top, and some pieces are great with just salt. For one piece I added both tonkatsu sauce and wasabi together and enjoyed it~


It's a Konkuk Univ. spot for a good, satisfying meal, so do visit Kosi~


After a lovely meal, I even got vitamins on the way out ^^ The staff at Kosi are all friendly, so if you're looking for a good restaurant in Konkuk Univ., definitely stop by~
