Nearest station: Gangnam Station (강남역) Exit 4 · ≈432 m≈ approximate, from map data (Kakao Map, Naver Map or map coordinates)
A seolleongtang (ox-bone soup) restaurant on Yeoksam-ro 7-gil, toward Exit 4 of Gangnam Station, open 24 hours, every day, with no break (Kakao Map and three blogs from August to October 2026 agree). So the day and hour do not matter. Seolleongtang was ₩13,000 per an October 2026 blog (Kakao Map's menu says ₩12,000). It is about a 7-minute walk (around 430m) from the station.

Tim Hortons Gangnam Station Daeryung Tower
팀홀튼 강남역대륭타워점A branch of the Canadian coffee-and-doughnut chain on the ground floor of Daeryung Tower, in front of Exit 5 of Gangnam Station. It opens at 07:00 on weekdays; Saturday opening is 07:00 per Kakao Map, Naver and a blog but 08:00 per DiningCode; Sundays and public holidays are 08:00. The Maple Ham & Cheese Melt is ₩6,900 and a medium Americano ₩4,000, so it suits a light breakfast of a sandwich and coffee.
Yangyangjip Apgujeong
양양집 압구정점A Korean-beef (hanu) haejangguk and seolleongtang restaurant about four minutes' walk from Exit 3 of Apgujeong Station. It opens early, which makes it a breakfast option on the Apgujeong and Sinsa side. Two September 2026 blogs give the opening time as 06:00 and Kakao Map as 07:00. Hanu yang-seonji haejangguk (tripe and blood-curd soup) is ₩13,000 and hanu yukhoe bibimbap (raw-beef rice bowl) ₩18,000, per Kakao Map and a blog. The blogs say it opens every day with no afternoon break.
Yeongdong Seolleongtang
영동설렁탕A long-running seolleongtang (ox-bone soup) restaurant in a side street of Jamwon-dong (Seocho-gu) — across Gangnam-daero from Garosu-gil — 3–4 minutes' walk from Exit 5 of Sinsa Station, which comes up on the Jamwon-dong side. Kakao Map and two September 2026 blogs all list it as open 24 hours, every day, which makes it easy to drop by at dawn or for breakfast — but 15:00–17:00 is a break. The menu is just two items: seolleongtang at ₩15,000 and boiled beef (suyuk) at ₩52,000. Reviews say it gets busy enough at lunch to have a queue.
Boseung Hoegwan Gangnam Station
보승회관 강남역직영점A company-run branch of a sundae-gukbap (pork and blood-sausage rice soup) chain on Teheran-ro 1-gil, close to Exit 12 of Gangnam Station, open 24 hours. Sundae gukbap and pork gukbap are ₩11,000, and a one-person set with a soup plus boiled pork and sundae is ₩16,000. There is a bar counter for solo diners along the window, and you order with the QR code or tablet at your seat. Kakao Map and three September 2026 blogs all list it as open 24 hours.
