Station, serving house-made udon and hand-breaded pork katsu. A late dinner at Kosi covered zaru udon on its own, a kama butter udon set with tempura, a single order of katsu and a draft beer, and the chilled udon stayed firm to the last bite while the tempura came out crisp from the fryer. With a long counter-style table for solo diners and wider tables as well, Kosi suits both a date and a meal alone. ## Good to know - **Location**: Short walk from Exit 1, Konkuk Univ.

Even though I came for a late dinner, there were tons of customers. I only took photos of the empty tables :) Since it's close to Konkuk Univ. Station, it felt like a great spot for a date too! ![Single-row table seating good for solo dining](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-05-p3a6g-966.webp) ![Spacious seating area at Kosi Konkuk University Branch](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-06-1uice-966.webp) ![Menu page listing udon and katsu at Kosi](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-07-apqfd-966.webp) ![Menu page listing chilled and hot udon](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-08-1aksc-966.webp) ![Menu page listing katsu and gyudon](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-09-6wer6-966.webp) ![Menu page showing the set upgrade information](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-10-1qe7o-966.webp) ## Kosi menu and the 4,000 won set upgrade Kosi Konkuk University Branch offers a wide range of choices from chilled and hot udon to katsu and gyudon (beef rice bowl), and you can upgrade any dish to a set for an extra ₩4,000. So I chose zaru udon (single), kamabata udon + set (tempura), and katsu (single). The menu is well suited for solo dining too. I thought I definitely need to come back for lunch sometime! ![Ordered dishes laid out on the table at Kosi Konkuk University Branch](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-11-18wlq-966.webp) ## Zaru udon at Kosi: served with salad and inari sushi First up, the zaru udon I was most looking forward to~ It arrived beautifully plated in a pretty bowl, which put me in a good mood. ![Zaru udon served in a bowl at Kosi](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-12-rioag-1200.webp) True to a house-made noodle shop, the visuals were amazing. Just looking at it, you could tell how chewy the noodles would be! It also came with salad and inari sushi (fried tofu pouch rice), making the meal even more filling. The filling was packed and fluffy, and so tasty. The seasoning was just right too, honestly delicious haha. ![Inari sushi and salad served alongside the zaru udon](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-13-k7dad-966.webp) ![Cross-section of a fully filled inari sushi](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-14-17i9r-966.webp) ![House-made udon noodles dipped in sauce](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-15-178tu-966.webp) Dipped fully in the sauce, it was pure chewiness — the noodles were thick and there was plenty of it. Since it's chilled udon, I could enjoy it deliciously the whole time without it going soft. The food came out beautifully plated too, and being able to taste zaru this good — I loved it~~ ![Table setting with zaru udon and a set meal together](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-16-mf748-966.webp) ## Kama butter udon set with tempura and a draft beer The kamabata (butter udon) I ordered as a set ~ ![Assorted tempura of perilla leaf, sweet pumpkin, shrimp, and sweet potato](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-17-1wpwe-966.webp) The tempura came out in a nice variety — perilla leaf, sweet pumpkin, shrimp, and sweet potato — so I thought it'd be great to share. Since they fry it fresh right after ordering, the tempura was incredibly crispy. In the end I added a cold draft beer~~ haha. One sip and all the fatigue from the day just melted away. ![Draft beer and kamabata udon set on the table](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-18-pufds-966.webp) True to its name, it comes with butter mixed in along with egg yolk and cheese powder — a combination that's bound to be delicious~~ They mix everything evenly together with the ingredients. ![Kamabata udon topped with egg yolk and cheese powder](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-19-1sp5b-966.webp) ![Kamabata udon with ingredients mixed evenly together](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-20-v9iat-966.webp) Aahh, the savory butter flavor plus the cheese powder — need I say more~~ The house-made noodles themselves have such a great chewy texture that I feel like they'd pair well with any menu item. ![Close-up of noodles lifted from the kamabata udon](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-21-qw27n-966.webp) ## Katsu at Kosi: thick pork and a crisp coating The udon was super tasty, but the katsu's visuals were also incredible. ![Thick-cut katsu served at Kosi](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-22-e4l3x-966.webp) ![Cross-section of the katsu showing its crispy coating](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-23-nx03f-966.webp) Just looking at the breading you could tell it'd be crispy, and most of all, look at the thickness of the meat,, dipped fully in the sauce, it was truly delicious!! The meat was very tender and combined with that crispy texture — I officially recognize this as a katsu place worth visiting near Konkuk Univ. Station~~ ![A piece of katsu served with wasabi](https://img.superchart.com/images/koshi-konkuk-zaru-udon-kama-butter/koshi-konkuk-zaru-udon-kama-butter-24-1h3s8-966.webp) Enjoying it with wasabi was delicious too haha. Since the meat was so~ thick, it also worked well as a solid, filling meal :) ## Is Kosi Konkuk University Branch worth a visit? Every single dish I ordered was delicious, making me want to try all the other menu items too — a restaurant with a clean interior that works well both as a date spot and for solo dining. The spacious layout meant I could enjoy the meal without feeling cramped~ I really love noodle dishes in general, so I think I'll definitely come back! Today was another enjoyable evening thanks to delicious food. Next time I'll have to come challenge the donburi (rice bowl) too. ## Where it is - Kosi Konkuk University Branch (코시 건대점) - 197 Achasan-ro, 1F, Gwangjin-gu, Seoul, South Korea - 서울특별시 광진구 아차산로 197 1층 - 37.5419061, 127.0654995 - Google Maps: https://www.google.com/maps/search/%EC%BD%94%EC%8B%9C%20%EA%B1%B4%EB%8C%80%EC%A0%90/@37.5419061,127.0654995,17z --- Superchart · https://superchart.com/en/@seoul-door-curtain/koshi-konkuk-zaru-udon-kama-butter/ · https://superchart.com/llms.txt
