We enjoyed yeolmu barley rice, plentiful seafood, and noodles from a second-floor window seat, and the broth grew richer with every bite. Verdict: a warm, filling alternative to grilled clams in Oido! 😊 ## Good to know - **Hours**: Mon, Tue, Thu–Sun 11:00–22:00; last order 21:10 - **Wednesday hours**: 11:00–16:00; last order 15:10 - **Menu & price**: Seafood whole-pot kalguksu for 2: ₩42,000 - **Add-on & price**: Yeolmu barley rice add-on: ₩1,500 - **Seating**: First and second floors, with window seats - **Waiting**: Catchtable kiosk and waiting chairs at the entrance *as written by the visitor on Sep 11, 2026* I went to 52 Degree Kalguksu Oido Main Branch (오십이도칼국수 오이도본점) because I wanted kalguksu (knife-cut noodles) with seafood in Oido. The building is pretty big from the outside, so it was easy to find—and Oido Sea is right in front, so the location is great too 🌊 ## 52 Degree Kalguksu Oido Main Branch: location and hours ![52 Degree Kalguksu Oido Main Branch information](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-01-gy3mo-900.webp) Mon, Tue, Thu–Sun 11:00–22:00 Last order 21:10 Wed 11:00–16:00 Last order 15:10 Wednesday has shorter hours, so I recommend checking the time before you go! ![52 Degree Kalguksu business hours](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-02-asyew-900.webp) ## First- and second-floor seating, plus a waiting area The restaurant is split across the first and second floors. There were quite a lot of tables on the first floor too, and everything was clean overall. ![First-floor seating inside 52 Degree Kalguksu](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-03-nzg5z-900.webp) ![First-floor table area at 52 Degree Kalguksu](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-04-1v6vd-900.webp) There is a separate Catchtable kiosk at the entrance, along with chairs for waiting beside it. It seemed like it could get busy on weekends or at mealtimes, so making a reservation beforehand might be even better! ![Catchtable kiosk and waiting chairs](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-05-da02d-900.webp) We went up to the second floor, and it was nearly full too 👀 The tables were spaced nicely, and there were more seats than I expected, so it seemed perfectly suitable for a group or family gathering. ![Second-floor seating area at 52 Degree Kalguksu](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-06-1pmac-900.webp) And on the second floor, the window seats are definitely the best,, ✨ The tide was out when I visited, but Oido Sea stretched out beyond the floor-to-ceiling windows, so it seemed lovely to watch the sea while eating. If you can get a window seat, I absolutely recommend it! ![Oido Sea seen from a second-floor window](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-07-19z3l-900.webp) ![Window seats overlooking Oido Sea](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-08-1yolf-900.webp) ![Second-floor window area at 52 Degree Kalguksu](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-09-sxm4d-900.webp) ![View of Oido Sea beyond the floor-to-ceiling windows](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-10-1pubq-900.webp) ![Dining area facing Oido Sea](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-11-teo43-900.webp) ![Window-side table at 52 Degree Kalguksu](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-12-1a5t1-900.webp) ## Tablet ordering and yeolmu barley rice You order on the tablet at each table. We came for the kalguksu, but they also had ramyeon, and the menu came with photos, which made choosing easy. ![Tablet ordering screen and menu information](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-13-nnkph-900.webp) ![Tablet menu with photos](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-14-j1czi-900.webp) Before the main dish arrived, yum yum—starting with the little serving of yeolmu (young radish kimchi) barley rice 🥄 I mixed the yeolmu into the barley rice, and its tangy, spicy flavor really woke up my appetite, haha. It is a tasting portion, but you can add more for ₩1,500 if you want! ## Seafood whole-pot kalguksu loaded with seafood Seafood whole-pot kalguksu for 2: ₩42,000 ![Seafood whole-pot kalguksu topped with octopus and crab](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-15-18c4p-1200.webp) As soon as it arrived, it was seriously piled high with seafood!! Octopus, crab, shellfish, abalone, shrimp, and thinly sliced beef belly were packed onto a huge platter, so the visual made quite an impression right from the start 🦀🐙 Once the dish comes out, a staff member pours in the broth. The clear broth starts gently bubbling among the seafood, and from that moment on, it smells so good,, With so much seafood in there, I could not wait to see how delicious the broth would be 🤤 Once the broth starts boiling, turn the crab over now and then so it cooks evenly! 🦀 Octopus can turn tough if it cooks too long, so we took it out first once it was cooked enough. It was chewy but softer than I expected. We also briefly cooked the thinly sliced beef in the broth, and its savory flavor went surprisingly well with the seafood! A staff member prepares the crab for you so it is easy to eat. It is more work than you might think, so it was convenient to eat it right away without wrestling with it myself, haha. The crab flavor seeped right into the broth too, making it richer as time went on. ![Staff-prepared crab and seafood broth](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-16-eeznn-900.webp) ![Seafood in the seafood whole-pot kalguksu](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-17-kaw1x-900.webp) A bite of abalone too 🦪 It had that bouncy, chewy texture, and opening the shellfish one by one was fun as well. There was not just one or two kinds, so after picking through all sorts of things, I was already pretty full before we even added the noodles ㅠ hahaha Once you have eaten a good amount of seafood, it is finally time to add the kalguksu noodles we had been waiting for!! The broth had already absorbed all the flavors of crab, shellfish, shrimp, and beef, so there is no way noodles added to it could taste bad 🥹 It did not end with the seafood—finishing with a hot bowl of kalguksu made the meal feel properly hearty! ![Kalguksu noodles added to seafood broth](https://img.superchart.com/images/oido-seafood-kalguksu-oido/oido-seafood-kalguksu-oido-18-1ygkn-900.webp) ## A plentiful meal in Oido After the meal, there was even mouthwash by the counter for anyone who needed it! Such a thoughtful little detail too,, 💕 At 52 Degree Kalguksu, we had a generous meal all at once, from seafood and thinly sliced beef belly to kalguksu at the end! With such a variety of seafood, it was fun for two people to pick and choose what to eat, and I loved how the broth became richer as we ate, haha. If you are looking for hot, plentiful seafood kalguksu rather than grilled clams in Oido, I recommend 52 Degree Kalguksu Oido Main Branch! 😊 ## Where it is - 52 Degree Kalguksu Oido Main Branch (오십이도칼국수 오이도본점) (오십이도칼국수 오이도본점) - 113 Oido-ro, Siheung-si, Gyeonggi-do, South Korea (경기도 시흥시 오이도로 113 1,2층 오십이도칼국수 본점) - 경기도 시흥시 오이도로 113 1,2층 오십이도칼국수 본점 - 37.3478439, 126.6917062 - Google Maps: https://www.google.com/maps/search/%EC%98%A4%EC%8B%AD%EC%9D%B4%EB%8F%84%EC%B9%BC%EA%B5%AD%EC%88%98%20%EC%98%A4%EC%9D%B4%EB%8F%84%EB%B3%B8%EC%A0%90/@37.3478439,126.6917062,17z --- Superchart · https://superchart.com/en/@gyeonggi-diner-stamp/oido-seafood-kalguksu-oido/ · https://superchart.com/llms.txt
