Seafood hotplate for three at Onda, a Mukho Port restaurant in Donghae

I recently visited Mukho! It's been super hot there since last winter?!? So I finally went haha 😙

While thinking about lunch on the second day, I went to 'Onda' Donghae Mukho Main Branch, which my partner had heard was delicious. It's a restaurant specializing in seafood hotplate dishes packed with fresh seafood.

How long is the wait? Arriving before opening at Onda

As a famous Donghae Mukho restaurant, waiting is basically a given?! We were the very first customers on an opening run. You just sign your name on the waiting sheet, and there's a dedicated waiting space on the 1st floor, which seems great for both midsummer and midwinter!

Inside Onda: the ocean-view window seats facing Mukho Port

Here's the interior. There are so many tables, so it works for solo dining all the way up to group gatherings! By the way, Onda (ONDA) means 'wave' in Spanish.

The sea's specialness is in its waves, and a great restaurant's specialness is in Onda!

The ocean view was amazing, so the whole meal felt like pure healing, just staring at the water. They seemed to seat window tables first haha. Go early and grab a window seat!

Each table is set up for two people, and water and sauces are brought after you're seated.

Before eating, they read through the instructions for how to eat the seafood hotplate.

They don't only have the seafood hotplate — there's also a beef belly hotplate, just so you know! We had the seafood hotplate for three haha.

Aprons are on the wall, so just grab one and use it.

Is Onda good with kids? Nursing room and high chairs

The restrooms are separated for men and women inside. Unusually for a Donghae Mukho restaurant, Onda even has a nursing room...! Baby chairs and a microwave were there too, of course. Highly recommend this Mukho restaurant for visiting with kids!

Side dishes and jumeokbap (rice balls) at Onda

The side dishes came out. Corn salad, bean sprouts, white kimchi, cubed radish kimchi, seasoned radish, braised potatoes, and pickled lettuce — the braised potatoes were seriously delicious!

We also ordered a rice ball. I'm someone who has to have a rice ball with anything soup-based,, 😏

My partner rolled it into round shapes haha. It tasted sweet and bold, exactly the kind of flavor that neutralizes the spiciness. If you're visiting with kids, they'd really love this!

What comes in the seafood hotplate for three, and how fresh is it?

Our seafood hotplate for three arrived! The visuals were seriously wild.. there was so much in it?! The staff explained the cooking method once more as they brought it out.

And the freshness was insane,,,, the abalone was still wriggling. Onda's day apparently starts at Mukho Port before dawn. Octopus, abalone, and all kinds of seafood pulled up by the boat owners become that day's dishes. No frozen ingredients, no compromises, no substitutes, ever! Freshness for the win 👍🏻 They personally clean the seafood sourced fresh every dawn.

This year's king prawn season hadn't even started for me yet, and I had my first one here haha. There were 3 prawns for the three-person portion!

They said the octopus comes out already cooked, so it's fine to eat right away. They cut it into bite-sized pieces for us first.

And the clams inside were really well de-sanded. Not a single empty shell either — every one of them was packed with plump meat. We shelled them all out to eat easily 🤤

The king prawns were plump too~ By the way, they'll bring you vinegar-chili sauce (chojang) if you ask. You know king prawns have to be dipped in chojang, right?

And what surprised me was that there was bunmoja (sweet potato starch noodles) in there!!! Flower-shaped bunmoja. I hadn't had it in a while and it was so good I seriously debated adding an extra portion.

Then they let it simmer away. Honestly while eating I wondered if the broth was too little, but as the vegetables wilted, more liquid came out. Just keep letting it simmer!

How does Onda's seafood hotplate taste, and how spicy is it?

Then we dug into the abalone and meat. Seafood like abalone and octopus was genuinely delicious 🤤 the kind of taste that instantly explains why this is a Donghae Mukho restaurant! That bouncy texture in every bite was no joke?!

The sauce was a soy sauce and wasabi blend, which paired perfectly with the meat,, 🤤

The portion was plenty even for three people! We were full but couldn't give up on the fresh seafood, so we said let's just eat the seafood.. hahaha. The spice level is on the hotter side. I'd say it's a bit spicier than Shin Ramyun.

Coffee vending machine at Onda for a palate cleanser

There's also a coffee vending machine on one side, so you can make yourself a cup!

On the way out there are mint candies for a palate cleanser, plus toothpicks and dental floss.
