It was so delicious that I had to share the story. The food was great, of course, but the ocean view absolutely made it…!!🐙🌊 ![Visit photo at Onda Donghae Mukho Main Branch in Mukho, Donghae](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-01-hfq2e-900.webp) The address is 151 Ilchul-ro, Donghae-si, Gangwon State, and parking is available. There was plenty of parking space right in front of the restaurant too! ![Exterior and parking area at Onda Donghae Mukho Main Branch](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-02-rk8qa-900.webp) ![Front of Onda Donghae Mukho Main Branch](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-03-i01lv-900.webp) We arrived first and were shown upstairs to the second floor—off we go! ![Stairs leading to the second-floor dining area](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-04-p1yhb-900.webp) ## An ocean view of Mukho Sea at a glance 🌊 At Onda, the dining area is upstairs, reached by taking the stairs from the first floor. Honestly, when I first saw the exterior, I had no idea the view would be this good. But then I got to the second floor and—surprise!—the East Sea stretched out refreshingly beyond the huge floor-to-ceiling windows. If you sit by the window, you can gaze at the blue sea throughout your meal. The weather was clear on the day I visited too, so the sky and sea were absolutely gorgeous. I took sooo many photos before the food even arrived, haha. If you are looking for an ocean-view restaurant in Mukho, I highly recommend a window seat! This ocean view is seriously crazy good..!!🌊 The weather made it extra pretty, right? ## Octopus, seafood, and thin-sliced beef grill menu and order Onda’s signature dish is its octopus, seafood, and thin-sliced beef grill, piled generously with octopus, abalone, clams, and all kinds of seafood. It costs ₩58,000 for two people, ₩78,000 for three, and ₩98,000 for four. We ordered the two-person serving and added fried rice. ![Octopus seafood thin-sliced beef grill menu guide](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-05-1b0vb-900.webp) ## How to simmer it deliciously yourself This place uses a self-cooking system, so if it is your first visit, it is helpful to read the “How to Eat Octopus Seafood Grill” guide posted on the wall! The octopus and clams arrive partially cooked, but the clams need to simmer a little longer with the other ingredients so their refreshing flavor properly infuses the broth. For baekhap clams, separate the flesh from the shells, and cook the abalone with the shell facing upward. Cut the octopus and vegetables into bite-sized pieces, then let everything bubble away and you are ready to eat🔥 The key is controlling the heat so the broth does not reduce too much! Dip the thin-sliced beef in the sauce served alongside it, and they recommend cooking the abalone thoroughly before having the fried rice. Also, dining time is limited to 1 hour and 30 minutes, so keep that in mind. At first, I wondered whether the self-cooking setup would be a bit of a hassle, but it was fun simmering everything to exactly the doneness we wanted. As time passed, the seafood flavor seeped into the broth and it became richer and richer—that was the charm of it😋 ![Self-cooking instructions for the octopus seafood grill](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-06-1u98i-900.webp) ## Banchan and sweet wasabi soy sauce The side dishes were mostly things that went nicely with seafood: braised potatoes, corn macaroni salad, lettuce salad, bean sprouts, white kimchi, kkakdugi (cubed radish kimchi), and more! The dish was spicier than I expected, so I had the corn macaroni salad here and there—it was nice for calming the heat!! ![Side dishes served with the seafood grill](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-07-6v8ae-900.webp) ![Corn macaroni salad and side dishes](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-08-3yd3w-900.webp) ![Side dish selection for the seafood grill](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-09-we2dt-900.webp) ![Wasabi soy sauce served with the griddle dish](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-10-1wbb9-900.webp) The special sauce served with it was wasabi soy sauce. Rather than being overly salty, it had a subtle sweetness to it?! At first I thought, “Why is this wasabi soy sauce slightly sweet?” But once I tried it with the savory, spicy seafood grill, I understood immediately, haha. The sweet sauce gently balanced out the spicy kick of the food, so the pairing was really good. It went especially well with a piece of thin-sliced beef dipped right in! 😋 ## A grill topped with whole octopus and live abalone The octopus, seafood, and thin-sliced beef grill had incredible visual impact from the moment it arrived! A huge griddle was piled high with whole octopus, live abalone, clams, thin-sliced beef, mushrooms, and vegetables—just looking at it made me feel full, haha. Hehe.. I love a generous spread like this🥰 Since the whole octopus arrives already cooked once, you do not need to cook it for long. Just cut it into bite-sized pieces and let it bubble with the other ingredients🐙🔥 ![Griddle topped with whole octopus and seafood](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-11-bo3en-1200.webp) The big live abalones in particular really made it feel like a proper Donghae trip! Not going to lie, I felt a tiny bit sorry for them because they were alive…>< It was not only seafood, either—the thin-sliced beef was included too, making it a good choice for seafood lovers and meat lovers visiting together. ![Seafood grill with live abalone and thin-sliced beef](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-12-fyn5d-900.webp) ![Ingredients in the octopus seafood thin-sliced beef grill](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-13-1x3fg-900.webp) Eat the octopus before it cooks too long and you can really enjoy its springy texture. The abalone was chewy too, and picking out the clams one by one was fun, so there was honestly much more to eat than I expected. The thin-sliced beef, fully coated in seasoning, was especially delicious. With meat tucked between all the seafood, I just kept reaching for more! ![Octopus seafood thin-sliced beef grill being cooked](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-14-17zyo-900.webp) It tasted even better with the ocean view, and eating it with someone I love made me so happy. ![Seafood grill enjoyed with an ocean view](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-15-ldwwq-900.webp) ![Dining area with a view of Mukho Sea](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-16-75yz1-900.webp) At first, the ingredients are heaped up high, but as they begin to simmer, the vegetables wilt and the seasoning permeates everything. Vegetables such as bean sprouts and enoki mushrooms release moisture, creating just enough broth. The spicy-sweet seasoning, savory seafood umami, and rich flavor of the thin-sliced beef all come together—it is a total rice thief! It was spicier than expected, so anyone who cannot handle spice should probably ask for it less spicy. I love spicy food, so I enjoyed it!! Dip it into the sweet wasabi soy sauce and that is the kicker..! The plump octopus and abalone were both excellent too!! They were both so good that we ate them super quickly. ## You absolutely have to save room for fried rice 🍚 Once you have had a griddle dish, you cannot leave without fried rice, haha. After eating most of the ingredients, cut the remaining bits up small with scissors, add rice, and quickly stir-fry it with the remaining sauce and roasted seaweed flakes—K-dessert complete! The fried rice was ₩3,000, and it was ₩3,000 worth of happiness! The griddle was already full of umami from the seafood and meat, so having the fried rice made it feel like a proper finish. Scraping up even the slightly crisp bits was so fun that I could not put my spoon down, even though I was full…🤣 ![Fried rice stir-fried in the griddle seasoning](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-17-17n6d-900.webp) ![Fried-rice preparation after the seafood grill](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-18-18bcs-900.webp) ![Griddle fried rice with roasted seaweed flakes](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-19-jb1zc-900.webp) ![Fried rice made with the seasoning left on the griddle](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-20-2fc6s-900.webp) ![Griddle fried rice turning golden](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-21-1oovg-900.webp) ![Fried rice full of seafood umami](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-22-6vgrn-900.webp) ![Finished griddle fried rice](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-23-1gvhq-900.webp) After the meal, we could also use the coffee machine set up in the restaurant. A warm cup of coffee was just perfect for refreshing my palate after the spicy griddle dish. More than anything, I think the biggest appeal of Onda Donghae Mukho Main Branch is being able to enjoy such a generous seafood grill with the Donghae Sea right in front of you. ![Coffee machine available after the meal](https://img.superchart.com/images/mukho-oceanview-seafood-grill-onda/mukho-oceanview-seafood-grill-onda-24-3xe17-900.webp) If you are traveling in Mukho and want a seafood dish a little different from raw fish or mulhoe (cold raw-fish soup), I recommend it! You can heartily enjoy whole octopus, abalone, clams, and thin-sliced beef, then finish properly with fried rice. If you want to tick off all three—great food in Donghae Mukho, an ocean view, and generous seafood—in one go, give Onda Donghae Mukho Main Branch a visit🌊🐙💙 ## Where it is - Onda Donghae Mukho Main Branch (온다 동해묵호본점) - 151 Ilchul-ro, Donghae-si, Gangwon State, South Korea (강원특별자치도 동해시 일출로 151) - 강원특별자치도 동해시 일출로 151 온다 - 37.5561197, 129.1207731 - Google Maps: https://www.google.com/maps/search/%EC%98%A8%EB%8B%A4%20%EB%8F%99%ED%95%B4%EB%AC%B5%ED%98%B8%EB%B3%B8%EC%A0%90/@37.5561197,129.1207731,17z --- Superchart · https://superchart.com/en/@ridgeway-supper-map/mukho-oceanview-seafood-grill-onda/ · https://superchart.com/llms.txt
