Gangdajim Samgak-gimbap Seongsu-jeom
강다짐 삼각김밥 성수점 Gangdajim is a native Korean word for eating rice on its own, without soup, water or side dishes — the name of a chain that sells made-to-order rice triangles.
Compiled from 8 blog posts read in fullSources →
The Seongsu branch of Gangdajim, a rice-triangle chain, at 18 Achasan-ro 7-gil. It makes rice triangles to order, boxes each one, and also sells tteokbokki, noodles and chicken — takeout and delivery only, with nowhere to sit. We read 26 posts from May 2025 to September 2026; 8 describe going to this shop, and all eight took their food away. Recorded prices: extra-topping tuna-mayo 2,700 won, extra-topping spicy pork 3,000 won, icy kimchi cold noodles 8,500 won (June 2026). In February 2026 gogi-buchujang was renamed Gangbibim and the basic Gangdajim triangle gained beef, pickled radish and seaweed. Fourteen posts were about other branches or a May 2026 pop-up booth and were set aside.

Counted from what bloggers wrote in their posts; we did not confirm it with the restaurant. Where the values differ, it may be a change over time rather than a disagreement, so we show when each one was written.
What sets it apart
- There is nowhere to eat in. Three posts say so outright, and a sponsored post describes a small room with just space to order and wait. A June 2026 post calls the front room clean and modern, but does not say anyone sat down.
- You order at a kiosk: five of the eight visits mention it, one noting an option to leave out cucumber. One visitor pre-ordered pickup through a delivery app and collected it straight away.
- Two posts paid with vouchers — the 2025 consumer-support payment in July 2025 and Onnuri vouchers in January 2026; one notes the support payment only worked for in-store orders.

Where it is
We could not find this shop’s own listing on Naver Map, so the link searches for its Korean name around this spot instead.
From the station
2 posts say it is walkable from the station.
Getting inside
The address says ground floor, but no visitor described the floor or any steps.
No one mentioned a step at the door or wheelchair or stroller access — we don't know, not that there is none.
No post mentions a toilet; as a takeout-only shop, visitors likely never needed one.
No one mentioned: Second floor · In a basement · Lift to the floor · Ramp at the door · Step at the entrance · Step-free access · Toilet inside · Accessible toilet · Separate restrooms. That is not the same as there being none — it means we could not confirm it. Worth calling ahead, and do tell us: we will put it here.

Posts that followed a TV spot
Of the 12 posts we gathered, 4 went up on a single day right after a TV spot and show no sign of a visit. They retell the broadcast, so we left them out of the counts.
We do not discard them. That a TV spot produced a burst of posts is itself something worth knowing about a place, and a star rating will not show it.

What we do not know
- Opening hours appear in six posts, all copied from listing blocks. Five, from May 2025 to February 2026, say 9 a.m.–9 p.m. and closed Fridays; one June 2026 post gives Sun–Thu 9–9, Fri 9–4, Sat 9–3. The hours seem to have changed in between, but no post records an announcement.
- Prices are patchy: only two single rice-triangle prices (2,700 and 3,000 won, June 2026), plus one January 2026 post that paid 3,800 won for two. No post totals a meal.
- Portions split: one post found the cold noodles very filling, while two found the rice triangles and chicken modest — one suggests buying two triangles.
- Only one post mentions waiting — delivery riders and customers queueing — and none gives a time.
- Two posts put it a 4–5 minute walk from Seongsu Station exit 1; nobody wrote about buses.
- Company is barely mentioned — one post bought dinner with her partner or brother; as a takeout shop, few posts say who they were with.
- Five posts copy the phone number 02-462-0498, but none says whether phone orders or reservations are taken; the one visitor who pre-ordered used a delivery app.
- Four February 2026 posts describe the menu renewal in identical phrases and order; none is marked sponsored, but they read like one brief, so treat their taste notes as a single voice. The premium single-variety rice claim is the chain's own wording.
