Guui Station Chinese restaurant with kids: cold jjamppong, Hyeongjeae

In short

Hyeongjeae Guui is a Hong Kong-style Chinese restaurant at 421 Achasan-ro, 1st floor, in Gwangjin-gu, Seoul. On a weekend visit at 1pm with a Naver reservation, the table ordered two ganjjajang (black bean noodles) at 9,000 won each with one jumbo portion, sweet and sour pork for 2–3 people at 22,000 won, and cold jjamppong (chilled spicy seafood noodles) at 12,000 won, and the room-like divided tables made it easy to sit with children. The cold jjamppong tasted unusual, like mul-naengmyeon broth with a smoky kick, while the sweet and sour pork came with too little sauce for anyone who likes to pour it over.

A Chinese restaurant worth knowing about in Gwangjin-gu: Hyeongjeae

Whenever I pass by this place near my house, it always seems packed for both lunch and dinner. It hasn't been open that long, but it already feels like a local favorite 👍 The kids wanted jjajangmyeon, so off we went to Hyeongjeae Guui, a Chinese restaurant near Guui Station. Let's go-🎶

That good-restaurant feeling creeps in just from the exterior 🍜 I don't usually eat Chinese food, so it's a rare treat for me, but I thought Hyeongjeae was a must-visit.

Weekend lunch wait and Naver reservations

We visited around 1pm on a weekend. Walking in, the tables were completely full. We had booked through Naver reservations. If you're coming on a weekend, I'd recommend reserving through Naver.

Room-style tables that work for families with kids

As break time approached and customers cleared out, I quickly snapped some photos. Each table is divided into room-like sections, so you can enjoy your Chinese food privately — a good spot for family gatherings or any kind of get-together.

It'd also be nice for a couple's date 😎

The smell of the food drifting around-🍜 There's an open kitchen right at the entrance, so you can watch the cooking happen and see that the place is kept clean.

Danmuji (pickled radish) and onions are self-serve. Just take as much as you'll eat, haha.

Hyeongjeae Guui is run by two brothers who reinterpreted Chinese cuisine in their own style, building on 30 years of know-how from their parents' Chinese restaurant. The original location is in Bangi-dong, Jamsil.

Kiosk ordering and what we ordered

You can order from the menu right at your table using the kiosk.

There are a lot of cooked dishes, so it looks like a great spot for drinks and food in the evening. Just note that dinner requires an alcohol order. My husband and I really wanted the dried tofu yangjangpi and yusanseul, but... the middle-schooler and elementary-schooler had already decided the menu.

What we ordered: two ganjjajang (₩9,000 each), one jumbo-size for our son (+₩2,000), an extra bowl of rice (₩1,000), sweet and sour pork for 2–3 people (₩22,000), and cold jjamppong (₩12,000).

Ganjjajang and how big the jumbo portion is

The ganjjajang came out first. I couldn't wait to take a photo of the full spread, so I don't have that shot 🤣 The jumbo portion is huge. Side by side, the difference is really noticeable.

It's been a while since I've seen quail eggs on jjajangmyeon. They also add cucumber, so it might help with blood sugar 😝

Not too sweet, and the meat pieces are big, so everyone just lost themselves and inhaled it.

Sweet and sour pork: not enough sauce

The batter on the sweet and sour pork looked thick from the outside, but it didn't feel thick when you bit into it.

The meat had some thickness too, kind of like eating a slightly thick pork cutlet. The sauce was very sweet-🍯 but the portion wasn't large, so dipping fully was a bit awkward. If you're a dipper, the sauce might leave you wanting more.

What cold jjamppong tastes like

Cold jjamppong is jjamppong with a cold broth and a special smoky sauce — my first time trying it. It's exactly like mul-naengmyeon (cold noodle) broth 🧊 The spicy seasoning keeps what could be a bland dish full of umami. It really did have that smoky flavor — I thought, this one's unusual — and enjoyed it cool on a hot day.

My son even added extra rice and cleared his whole bowl of jjajang-rice 👍 (He's a 6th grader who eats a lot, but I guess he wasn't full yet...?) Families with kids will relate — there are some menu items you just end up ordering no matter what. Still, when the whole family eats happily, it's a proud feeling. Especially when the kids like it. (This is the kind of mom I am... family love 🧡)

Another good meal today!
