The half-and-half katsu (₩13,500), katsudon (₩11,000), and zaru soba (₩10,500) showed off the stretchy cheese in the cheese katsu and a tsuyu mixed with grated radish and scallions. Kosi is a great spot to enjoy pork cutlet and soba together at one table. ## Good to know - **Location**: 466 Bongcheon-ro, 101ho, Gwanak-gu, Seoul, South Korea (3-min walk from Exit 6, Seoul National University Entrance Station) - **Hours**: Daily 11:00–20:50, break time 15:00–17:00 - **Parking**: Not available - **Signature menu**: Tori tempura bukkake udon ₩11,000 / Pork loin half-and-half katsu ₩13,500 - **Ordered**: Half-and-half katsu ₩13,500 / Katsudon ₩11,000 / Zaru soba ₩10,500 - **Seating**: 4-top and 6-top tables, counter (window) seats, kids' table available - **Ordering & payment**: Order and pay via tabletop kiosk - **Review event**: Vegetable tempura and sweet potato cheese korokke included with review event participation *as written by the visitor on Sep 7, 2026* Had a delicious dinner near Seoul National University Entrance Station.

As you approach, a clean wood-toned exterior greets you. ![Clean wood-toned exterior of Kosi Seoul National University Entrance Branch](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-02-k7lvr-900.webp) ![Entrance of Kosi Seoul National University Entrance Branch with signature menu photos displayed](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-03-u2p4q-900.webp) At the entrance, photos of the signature menu items are on display, so your eyes get to enjoy the food before you even walk in. ## An interior that works for solo diners and families with kids Inside, there are 4-top and 6-top tables, so it looks like it can seat groups too. (We took this photo after all the other customers had left, close to closing time.) There are also counter seats where you can look out the window while eating solo — and there were actually quite a few solo diners at the same time we were there! There's a kids' table too, so it's fine to bring children along. ### Table setting ![Table setting with an ordering kiosk at Kosi Seoul National University Entrance Branch](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-04-wjjob-900.webp) Ordering and payment are done through the kiosk on the table. ![Sesame, pepper, and salad dressing set on the table](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-05-rk6zh-900.webp) *Various sauces* Sesame, pepper, and salad dressing are set out beside it. ## The menu lineup ![Menu board at the entrance of Kosi Seoul National University Entrance Branch](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-06-1jgu5-900.webp) ![Menu board listing cold udon and tonkatsu](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-07-1c643-900.webp) ![Menu board listing kama udon and maze-on udon](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-08-1ykn0-900.webp) ![Menu board listing donburi and side dishes](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-09-17gbe-900.webp) I took photos of the menu board at the entrance. You can choose from cold udon, tonkatsu (pork cutlet), kama udon and maze-on udon, donburi, and side dishes — quite a range. ![Menu guide sign at Kosi Seoul National University Entrance Branch](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-10-1xohn-900.webp) We ordered ✔️half-and-half katsu ₩13,500 ✔️katsudon ₩11,000 ✔️zaru soba ₩10,500. Let me introduce each one! ## Zaru soba ₩10,500 ![Zaru soba topped with shaved ice, served with tsuyu and grated radish on the side](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-11-dooae-900.webp) *Zaru soba ₩10,500* The soba came out topped with fine shaved ice — cool and clean. On the side of the tsuyu broth was a separate plate of grated radish, scallions, and wasabi, so once you've poured the broth over, you can add the radish and scallion-wasabi to taste. Mix it all together and you get an even richer tsuyu. The cool, clean taste of the grated radish combined with the sharp wasabi and fragrant scallions to give it a savory, umami-packed kick. Dipping the soba noodles in fully is a real treat. ## Katsudon ₩11,000 ![Katsudon topped with egg and tare sauce](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-12-17a8w-900.webp) ![Close-up of a bowl of Kosi's katsudon](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-13-5sg6l-900.webp) Katsudon topped with fluffy egg and a savory tare sauce over the pork cutlet. ![A spoonful of katsudon with rice, egg, and pork cutlet together](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-14-meq95-900.webp) For the katsudon, the crispy pork cutlet soaked up the sweet, salty sauce, and it went especially well eaten together with the rice. You can see the size of the pork cutlet... Piling rice, egg, and pork cutlet onto one spoonful makes for a seriously filling bite. ## Half-and-half katsu ₩13,500 — the cheese katsu is the real deal ![Half-and-half katsu plate with classic pork cutlet and cheese katsu](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-15-cuult-900.webp) *Half-and-half katsu ₩13,500* The half-and-half katsu comes with a light, savory classic pork cutlet on one side and a cheese-stuffed cheese katsu on the other. ![Cross-section of the classic pork cutlet from the half-and-half katsu](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-16-hq8b9-900.webp) ![Dipping the pork cutlet in sauce](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-17-1lsig-900.webp) ![Pork cutlet served with wasabi and fine salt](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-18-h0i4a-900.webp) The classic pork cutlet tastes different depending on how you eat it — with wasabi on top, dipped fully in the tonkatsu sauce, or dipped in fine salt. ![A single piece of inari served alongside the half-and-half katsu](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-19-1oqgj-900.webp) ![Inari placed on the half-and-half katsu table setting](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-20-10ryy-900.webp) A cute single piece of inari (fried tofu pocket rice) comes alongside it. So nutty and good~! And now, the cheese katsu 👍🏻 We took one bite of the cheese katsu ![Cheese stretching long from the cheese katsu](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-21-112kq-900.webp) ![Lifting the cheese katsu with cheese stretching out](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-22-1qtdp-900.webp) Both when my partner ate it and when I ate it, the cheese stretched way out haha. The moment you bite in, the savory cheese pulls long and stretchy — a joy visually and taste-wise both. ## Vegetable tempura and sweet potato cheese korokke If you take part in the review event, you get vegetable tempura and sweet potato cheese korokke. ![Cross-section of sweet potato cheese korokke with stretchy cheese](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-23-4dkos-900.webp) Inside the crispy tempura batter is a sweet, soft sweet potato mousse packed with cheese. Can you see the cheese stretching? The sweetness of the sweet potato with the salty, savory cheese — a textbook case of sweet-and-salty. ![A plate of freshly fried vegetable tempura](https://img.superchart.com/images/koshi-seoul-univ-cheese-katsu-soba/koshi-seoul-univ-cheese-katsu-soba-24-1qrqf-900.webp) *Vegetable tempura* Freshly fried vegetable tempura, generously loaded with a variety of vegetables. The batter is thin and crispy, so the vegetables' natural crunch and subtle sweetness really come through. ## Final verdict Every single dish we ordered was delicious at Kosi, a Japanese restaurant near Seoul National University Entrance Station. - ✔️Half-and-half katsu: the best way to enjoy crispiness and cheesy savoriness at once - ✔️Katsudon: a hearty rice bowl with the perfect juicy, sweet-and-salty balance - ✔️Soba: clean and refreshing with fine shaved ice, pairs well with the pork cutlet All three main dishes were really delicious. If you're near Seoul National University Entrance Station and want great pork cutlet and soba, I'd recommend this place. ## Where it is - Kosi Seoul National University Entrance Branch (코시 서울대입구점) - 466 Bongcheon-ro, 101ho, Gwanak-gu, Seoul, South Korea - 서울특별시 관악구 봉천로 466 101호 - 37.4820226, 126.951605 - Google Maps: https://www.google.com/maps/search/%EC%BD%94%EC%8B%9C%20%EC%84%9C%EC%9A%B8%EB%8C%80%EC%9E%85%EA%B5%AC%EC%A0%90/@37.4820226,126.951605,17z --- Superchart · https://superchart.com/en/@restaurant-door-seoul/koshi-seoul-univ-cheese-katsu-soba/ · https://superchart.com/llms.txt
