Arriving late after overtime, the writer ordered the loin katsu at 14,000 won and the premium loin katsu at 16,000 won side by side to compare fat ratio and texture, and both came as a full table with kelp rice, Korean-style doenjang soup and gangjeong (sweet crisp candy) for dessert. With bar seats for solo diners and window seats for two, Katsu Monster works just as well for a quick dinner alone as for a date. ## Good to know - **Loin katsu**: 14,000 won - **Premium loin katsu**: 16,000 won (gabrisal, pork jowl-collar cut) - **Hours**: Fri–Tue 10:30–23:00 / Wed–Thu 10:30–21:00 - **Address**: Unit 101, 1st Floor, 42-6 Donggyo-ro 38-gil, Mapo-gu, Seoul - **Seating**: Bar seats, window seats for two, high chairs available - **Ordering**: Tablet ordering at every table - **Other menu items**: Udon, soba, curry and more - **How to order**: Dine-in, delivery and takeout - **Price reference**: ₩2,000 ≈ $1.4 (2026-09-19) *as written by the visitor on Sep 17, 2026* ## Where is Katsu Monster? At the end of the Miro-gil alley in Yeonnam-dong ![Exterior of Katsu Monster Yeonnam Main Branch at the end of the Miro-gil alley in Yeonnam-dong](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-01-1honv-966.webp) ![Full view of the entrance to Katsu Monster Yeonnam Main Branch](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-02-1fp0x-966.webp) I was craving Japanese-style tonkatsu (pork cutlet) again, so I visited Katsu Monster Yeonnam Main Branch (카츠몬스터 연남본점), a well-known spot in Yeonnam-dong 🐷 It sits right at the end of the Miro-gil alley. ![Sign noting hand-prepped domestic sirloin tonkatsu specialty restaurant](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-03-1b4mr-966.webp) It's a fusion tonkatsu specialty restaurant that hand-preps domestic sirloin and tenderloin every single day! ![Interior seating at Katsu Monster Yeonnam Main Branch](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-04-1fys3-966.webp) ![Interior view with bar seating for solo diners](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-05-n9qae-m-966.webp) ## Bar seats for solo diners and late hours until 23:00 Katsu Monster Yeonnam Main Branch has bar seating, so it's fine for eating alone, and it also seemed like a comfortable spot to come with friends or a partner. ![Window table seating for two](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-06-5zu3c-966.webp) ![Restaurant atmosphere seen from the window seat](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-07-tj96o-m-966.webp) The owner who served us was kind too. We settled into a window seat for two. Since the place stays open late, it was great for coming in for a late dinner after overtime work haha (Fri–Tue 10:30–23:00, Wed–Thu 10:30–21:00). ![Corner with baby chairs, mouthwash, and hair ties for guests](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-08-nbazb-966.webp) ![Guest convenience items set out on one side of the restaurant](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-09-1feiz-966.webp) Baby chairs, mouthwash, and hair ties placed around for guests — you could really feel the owner's thoughtful attention to detail. ## Tablet ordering at Katsu Monster: udon, soba and curry too Time to actually order. You can order easily via the tablet set up at each table haha. Beyond tonkatsu, there's a whole range of dishes like udon, soba, and curry too. ![Tonkatsu menu shown on the tablet ordering screen](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-10-iom2z-966.webp) ![Menu screen showing udon, soba, and curry options](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-11-fkwq2-966.webp) After some deliberation, we settled on the basic loin katsu and the special premium loin katsu 🙌 I ate in-store, but plenty of other customers were using delivery or takeout too. ![Tonkatsu sauce, wasabi, and salt set out on the table](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-12-18jn0-966.webp) For reference, tonkatsu sauce, wasabi, salt, and other condiments to add are set out on one side of the table like this, so feel free to help yourself. ## Loin katsu 14,000 won vs premium loin katsu 16,000 won ![Loin katsu and premium loin katsu set side by side](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-13-xo4yw-1200.webp) Ta-da — the dishes we ordered were ready in no time 😉 - 📌 Loin katsu ₩14,000 - 📌 Premium loin katsu ₩16,000 The visuals are seriously impressive — they fry it up crisp right when you order! ![Close-up of freshly fried tonkatsu](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-14-1iqyr-966.webp) They said if you sign up for notifications, you get a free mini spicy curry as an event bonus, so if you're interested, give it a try :-) ### Loin katsu with kelp rice and Korean-style doenjang soup ![Neatly arranged loin katsu full set](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-15-57h5w-966.webp) *Loin katsu* I started with the loin katsu first — everything came out as a neat, tidy set haha. ![Cabbage salad with dressing and a side of tonkatsu sauce](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-16-10zdo-966.webp) They pour plenty of dressing over the cabbage salad, and give you enough tonkatsu sauce to enjoy too. The soup that came with it was surprisingly not the usual Japanese miso soup but a Korean-style doenjang soup (soybean paste soup) — I was surprised how generously it was packed with meat, burdock root, zucchini, and cheonggyeongchae (young cabbage) haha. ![Korean-style doenjang soup packed with ingredients](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-17-td1kd-966.webp) Loin katsu is basically sirloin katsu — Katsu Monster's signature is frying it in clean oil with a perfect ratio of lean meat to fat. ![Cross-section of thickly cut loin katsu](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-18-2dvl2-966.webp) ![Loin katsu served with rice mixed with kelp](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-19-1tbwh-966.webp) It was a tonkatsu with a nicely crisp exterior and a thick, satisfying chew. The rice was also finely chopped with kelp mixed in, which set it apart from other places haha. ### Premium loin katsu: what the 2,000 won gabrisal upgrade tastes like ![Premium loin katsu full set](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-20-1q6ux-966.webp) *Premium loin katsu* This is the premium loin katsu (gabrisal, pork collar) 🐽, where the deep meaty flavor and savoriness really stand out. It's ₩2,000 pricier than the regular loin katsu, so naturally I was hoping it'd taste even better haha. ![Cross-section of the fattier gabrisal premium loin katsu](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-21-urora-966.webp) It has a higher fat ratio than the regular loin katsu and is a bit more tender. ![A piece of premium loin katsu topped with wasabi](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-22-1hz79-966.webp) I enjoyed it with a kick of wasabi on top, or simply dipped in salt to taste the pork's natural flavor. ![Tonkatsu dipped in salt](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-23-1l5qz-966.webp) ![Premium loin katsu sprinkled with shichimi](https://img.superchart.com/images/katsumon-yeonnam-roskatsu-comparison/katsumon-yeonnam-roskatsu-comparison-24-140yc-966.webp) Personally, sprinkling on some shichimi for a light kick of spice was also a nice treat :) It's a large portion, so finishing it left me really full!! ## Gangjeong for dessert: is Katsu Monster a good Yeonnam-dong date spot? For dessert, they brought out a sweet, crunchy gangjeong (Korean sweet snack), which rounded off the meal perfectly 🫠 Such a hearty, satisfying dinner. I'd recommend Katsu Monster Yeonnam Main Branch as a date course in Yeonnam-dong. ## Where it is - Katsu Monster Yeonnam Main Branch (카츠몬스터 연남본점) - 1st Floor, Unit 101, 42-6 Donggyo-ro 38-gil, Mapo-gu, Seoul, South Korea - 서울특별시 마포구 동교로38길 42-6 1층 101호 카츠몬스터 연남본점 - 37.5610304, 126.9255679 - Google Maps: https://www.google.com/maps/search/%EC%B9%B4%EC%B8%A0%EB%AA%AC%EC%8A%A4%ED%84%B0%20%EC%97%B0%EB%82%A8%EB%B3%B8%EC%A0%90/@37.5610304,126.9255679,17z --- Superchart · https://superchart.com/en/@seoul-soup-shelf/katsumon-yeonnam-roskatsu-comparison/ · https://superchart.com/llms.txt
