# Solo udon dinner with pork loin katsu in Gwanak, Seoul: Kosi - By Daeul (https://superchart.com/en/@seoul-highland-plates/) - Written Sep 13, 2026 - Local places › Restaurants › Gwanak, Seoul - Sponsored: This is a review of a visit made with support from the business. - English edition: https://superchart.com/en/@seoul-highland-plates/koshi-seoul-national-university-toriten-udon/ - Also in: [한국어](https://superchart.com/ko/@seoul-highland-plates/koshi-seoul-national-university-toriten-udon/index.md) ## In short Kosi Seoul National University Entrance Branch is a house-made Sanuki udon and pork loin katsu restaurant 144 meters from Exit 5 of Seoul National University Entrance Station in Gwanak, Seoul. On a chilly evening, this solo diner ordered the tori-ten udon (chicken tempura udon) for 11,000 won and added pork loin katsu, and the chicken thigh tempura alone was filling enough. Between the single-seat bar table and the group tables, Kosi is an easy choice whether you come alone or with a crowd. ## Good to know - **Location**: 1F, 466 Bongcheon-ro, Gwanak-gu, Seoul (144m from Exit 5, Seoul National University Entrance Station) - **Hours**: Daily 11:00–20:50 - **Break time**: 15:00–17:00 - **What I ordered**: Tori-ten udon 11,000 won + added pork loin katsu - **Seating**: Single-seat bar table, 4-person tables, group tables - **Service**: Takeout, delivery and group dining available - **Parking**: Available on weekends and holidays (if a spot in the building lot is free and has a sign, move the sign for 1 hour; the spots along the side of the building are often open) - **Price reference**: ₩11,000 ≈ $8.2 (2026-09-15) *as written by the visitor on Sep 13, 2026* I had an errand near Seoul National University Entrance Station and was looking for somewhere nearby for dinner when I spotted that 'Kosi' had been featured on the TV show Master in the House. It had suddenly gotten chilly out and I was craving warm udon, and since they make traditional Sanuki-style udon, I went in solo! The place was so clean and, more than anything, the food was so good! The portions were huge too, so it was great value! I don't usually eat a big dinner, but it was so tasty I finished the whole bowl! I'd definitely go back! If you're looking for a good restaurant near Seoul National University Entrance Station, I recommend trying the katsu and Sanuki udon at 'Kosi' :) ![Tori-ten udon and pork loin katsu spread at Kosi Seoul National University Entrance Branch](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-01-132fx-966.webp) ## Where is Kosi Seoul National University Entrance Branch?

The interior was really clean and the staff were friendly haha. It's an open kitchen too, so you could clearly see how carefully everything was kept clean :) ![View of the dining hall seating at Kosi Seoul National University Entrance Branch](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-07-11r7v-966.webp) With a bar table perfect for solo dining, plus 4-person and group tables, it looked like a great spot whether you're eating alone or coming with others! ![Solo bar table good for eating alone](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-08-1mhhv-m-966.webp) ![Wall-side table and group seating](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-09-1y45i-966.webp) Since I came to eat solo, I sat at the table against the wall! ## What's on the menu at Kosi Bukkake udon seemed to be Kosi's signature dish — it looked so good that I really struggled to decide what to order! I regretted coming alone since I could only order one dish — I wished I'd come with someone to share with... sigh. The menu was varied, with bukkake udon, tempura udon, katsudon, and gyudon (beef bowl) all on offer. ![Kosi's menu board listing bukkake udon, katsudon, and gyudon](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-10-1b9sl-966.webp) ## Tori-ten udon for 11,000 won with pork loin katsu added Tori-ten udon is ₩11,000 — udon topped with fried chicken thigh tempura. Since I really wanted a warm bowl of udon, I chose the tori-ten udon! They also had a set meal that comes with katsu. Since it felt like a waste to just have udon at a katsu specialist, I added the pork loin katsu too :) ![Sauces, toppings, and wet wipes set out on the table](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-11-1uybg-966.webp) Each table came with sauces and toppings already set out! Even wet wipes were provided — so tidy! ![Full table setting of tori-ten udon and pork loin katsu](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-12-19806-966.webp) Tori-ten udon plus katsu! I was shocked by how huge the portion was! The chicken thigh tempura alone on top of the udon looked like it could fill you up. The katsu was thick too — it felt less like an add-on and more like a full set menu! ![Table setting with thick pork loin katsu and udon side by side](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-13-1c1sv-966.webp) ![Sauces and salad served alongside the katsu](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-14-twyja-966.webp) The sauces and salad that came alongside! Wasabi and pink salt were served too, perfect to go with the katsu — the katsu sauce was really tasty too haha. ![Katsu plate with wasabi and pink salt on the side](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-15-ntr8d-966.webp) ### How thick is the pork loin katsu? Plus the inari sushi Can you see how thick the pork loin katsu is! The batter was crispy and the meat was really good too haha. One piece of inari sushi (fried tofu rice) came alongside it too! ![Cross-section of the thick pork loin katsu with inari sushi](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-16-rs3p5-966.webp) ### Kosi's udon noodles and portion size And the tori-ten udon! I want to come back just for this again! The noodles were really chewy and the tempura was crispy — the two went perfectly together! I usually eat small portions, but honestly the chicken thigh tempura alone filled me up!! ![Warm tori-ten udon topped with chicken thigh tempura](https://img.superchart.com/images/koshi-seoul-national-university-toriten-udon/koshi-seoul-national-university-toriten-udon-17-1deh1-1200.webp) Confirmed: katsu plus udon done right!
