Best Jjamppong in Seoul: Jjamppong Gaon, and Why I Went Back

 

I found this place by walking past it. That is the whole origin story. It is close to where I live, in a part of Seoul that no one visits on purpose, and one day I went in.

Four days later I went back. I have eaten at a lot of restaurants in this city. I do not do that.

Quick Verdict

> Order the chadol sukju jjamppong. It is the signature and it is why you came.
 > The bean sprouts are not garnish. They keep a heavy broth from feeling heavy.
 > You can choose your spice level. Choose carefully.
 > They give you a dipping sauce for a soup dish. Trust it.
 > Guui, not Gangnam. No tourists, no wait, parking out front.

You cannot see the noodles. That is not a mistake, that is the dish.

What Arrives at the Table

The dish is called chadol sukju jjamppong — brisket and bean sprout jjamppong. It is the house signature and it costs 13,000 won.

What arrives is a black bowl of red broth with a mountain built on top of it. Bean sprouts, thin sliced beef brisket, green and red chili scattered over. The noodles are down there somewhere. You will have to go find them.

The first thing I got from the broth was not the heat. It was the fire — that scorched, smoky edge a wok leaves on food when the flame is high enough and the cook is fast enough. Koreans call it bulmat, fire taste, and it is the single thing that separates a good jjamppong from a forgettable one. This broth has it.

The Bean Sprouts Are Doing Real Work

A jjamppong broth is built on chili oil and wok fat. By the middle of the bowl it can start to sit on you.

The sprouts here are cooked just enough and no further. They still snap. And because they go in at the end, they cool the broth slightly and cut it — the Korean word is siwonhada, which means cool and also means a hot soup that clears you out rather than weighing you down. Both meanings apply.

Korean Chinese food has a reputation here for being oily and not especially good for you. This restaurant feels like someone sat down and designed against that reputation on purpose.

This is my second visit. I did not plan a second visit.

They Give You a Dipping Sauce for a Soup

This is the part I did not expect, and it is the part I would tell a friend about first.

Jjamppong is a noodle soup. Nothing about it suggests dipping. But a small brown sauce comes to the table with it, and what you do is lift the sprouts and the brisket out of the broth, dip them, and eat them that way. Then you dig down, pull the noodles up, and eat those with the broth.

It is very good. I am not going to build a theory about why. It is just very good, and I would have missed it entirely if I had assumed the sauce was for something else.

Three sauces on this table and only one of them is the one you expect.

The Tangsuyuk Broke My Own Rule

I have a rule about Korean Chinese restaurants, and I have written it down elsewhere: if the kitchen pours the sweet and sour sauce over the tangsuyuk before it reaches you, that is confidence. They know the fried pork will hold. Sauce served on the side is the more cautious choice.

This restaurant does not serve the sauce on the side. It does not serve that sauce at all.

What comes instead is a soy and mustard sauce, sharp where the usual one is sweet. The first time I ate here I asked for the normal sweet sauce, because I like the normal sweet sauce, and they brought it out without any fuss. The second time I did not ask. The mustard one is better with this particular pork, and by then I knew it.

So the rule holds and this place is the exception, which is a more interesting outcome than the rule being wrong. The fried pork itself is soft inside and crisp outside, with none of the heavy pork smell that ruins the dish when the oil is tired.

Bean sprouts again. At this point it is clearly the house signature.

And yes, there is a mountain on the tangsuyuk too — bean sprouts and shredded scallion piled over the pork. The menu name for it is Achasan-deomi, Achasan pile, after the mountain that sits just east of here.

How Spicy, Honestly

You choose your heat level when you order. We took a middle setting, roughly where a Korean fire chicken noodle lands, and it was hot in a way I enjoyed rather than endured.

For most visitors that setting will read as genuinely spicy. It is worth attempting if you like heat. There was at least one level above ours on the menu and I did not try it, because I looked at it and decided I would lose.

The Side Dish Worth Noticing

The banchan starts out completely standard for a Korean Chinese restaurant: yellow pickled radish, raw onion, and a dish of black chunjang to dip the onion into. Every one of these places gives you those three.

Then there is a fourth one, and it is pa-kimchi — kimchi made from whole scallions, sharper and more pungent than the cabbage kind. I have not been given that at a Chinese restaurant before. I happen to love it. After the meal they bring plum tea.

Lunch. Nobody here is on holiday.

Who Should Actually Go

Go if you like heat and you specifically like the smoke of a hard wok flame. That is what this kitchen is good at and everything else follows from it.

Think twice if you want the familiar sweet tangsuyuk sauce as a default, or if you want a bowl you can eat without excavating it. And be honest about the geography: Guui is a residential neighborhood on the eastern side of the river, nowhere near anything you flew here to see. You would be making the trip for one bowl of noodles.

The view from the window seat. Parked cars, a side street, nothing else.

I make it regularly. It is close to where I live, and the room is full of neighbors having lunch.

Before You Go

It is busy but I have never waited, even at a meal hour. You order from a tablet at the table and pay at the table when you are done. Eating alone here is completely normal. There is parking directly in front, which in Seoul is worth saying out loud.

If you want the background first — why Korean Chinese food is its own cuisine, and where the sauce rule comes from — that is in my guide to Korean Chinese food (Coming Soon).
