A trip with my husband, finally, after such a long time! We went to Mukho in Donghae, a hot travel spot these days. When you travel, eating well matters, right? Since we were near the sea, we wanted seafood, so we looked up a Mukho restaurant called Onda. It was so delicious, and since it's a sea-view restaurant, eating good food while looking at the ocean made it doubly enjoyable, so I'm recommending it!

Where is Onda Donghae Mukho Main Branch?

Onda Donghae Mukho Main Branch is on Ilchul-ro in Donghae, directly across from Kkamak Rock. It's about a 10-minute walk from Dojaebigol, Mukho's popular tourist spot, so it's easy to get to!

When can you get a sea-view window seat at Onda?

By the time the break time (14:45~16:20) ended, the sea-view window seats at Onda were already taken. I arrived near the end of the break time and the window seats were full. If you come a bit before the break time ends and wait, I think you can grab a sea-view window seat!

The dining tables are on the 2nd floor, which has lots of space and roomy tables, and many families came too! If you avoid the lunch and dinner peak times, I think you can get a seat at Onda without a wait!

What side dishes come with a meal at Onda?

Onda side dishes including braised potatoes and white kimchi

Side dishes come out as soon as you sit down at Onda~ Braised potatoes, pasta corn salad, white kimchi, seasoned lettuce, seasoned pickled radish and seasoned bean sprouts: all easygoing sides that go well with the octopus seafood hotplate!

The octopus seafood hotplate for two at Onda was topped with a huge variety: big octopus, abalone, clams and even beef belly, and it looked generous! Since it was just my husband and me, we ordered the one for two.

Seeing the generous hotplate spread and how fresh it all looked, I thought, we were so right to come to Onda!

To eat the hotplate, first separate the clam meat from the shells of the white clams, and cook the abalone with the shell facing up~! Next, cut the octopus and vegetables into bite-size pieces~! And the fresh abalone doing the twist, haha. When I flipped it over to cook, it moved so wildly.

How does Onda's spicy red hotplate broth taste?

The broth is a red spicy broth that felt like Deungchon shabu-shabu (hot pot with thinly sliced beef and vegetables). Once you separate the clams, cook them and cut everything into bite-size pieces, you're ready to eat! Then you just simmer it well, haha. It tasted spicy and kick-in-the-throat sharp!

Once it's cooked a bit, eat the beef belly first, then the octopus, then the clams~~ The octopus and clams come already cooked, but the broth tastes better once they've steeped in it a while! It felt like eating shabu-shabu, and the sharp broth keeps it from feeling greasy. Truly a delicious Mukho restaurant!

When to eat the fried rice and abalone

The finish for Onda's octopus hotplate is fried rice. After picking out a good amount of the seafood and vegetables, I wanted rice, so I ordered the fried rice!! It comes with plenty of seaweed flakes and pickled radish, and you just stir-fry it right on the hotplate!

Fried rice on one side, the leftover seafood on the other, haha. We were told to eat the abalone around the time the rice is being fried, so it was fried rice with abalone, nom nom nom!! Eating live abalone freshly cooked is definitely fresh and so good~

The two of us ate Onda's signature octopus seafood hotplate, and we were full and had such a good time after a long while of a seafood binge. If you're wondering where to eat in Mukho, I recommend Onda's octopus hotplate, a combo of sea view and tasty food!!!
