Getting back

For what is actually running tonight, the map apps are the accurate answer. Below is what they cannot tell you.

Nearest station

Gayang Station, Line 9 (about 800m in a straight line)

Last train, weekdays 9호선 24:46 → 당산 · 24:59 → 마곡나루· weekend 9호선 23:44 → 당산 · 23:57 → 김포공항

No station sits right at the door. Gayang on Line 9 and Balsan on Line 5 are both about 800m away in a straight line, and the actual walk is longer. At night the direction matters: Gayang is the one that gets you back into central Seoul. Balsan's last Line 5 train only reaches Hwagok, one stop away (24:47 on weekdays, 23:43 on weekends); the trains that go further into the city leave earlier.

Times verified against operator timetables. Trains past midnight are written as 24:00+ the way platform boards do. Holiday or special schedules can differ - re-check in a map app on the day.

Near here, after the show

Late food Cafés Pubs & bars Clubs

Clubs fill up after 10pm and run until dawn. Bring your passport - the door will check ID. Entry policies vary from place to place, so it is worth having more than one in mind.
Last subways vary by line but generally go around midnight. Shows usually end between 10 and 11pm, so leaving promptly you will normally make it - it is the merch queue and the photos that cost people the train.
After the subway stops, night buses numbered with an N run until roughly 3–4am. Your T-money card works on them, and the routes show up in any map app.
The street outside a venue at closing time is the hardest place in the city to find a taxi, and the hailing apps usually want a Korean phone number. Walking five minutes to a main road is normally faster than waiting.
Look up your way back before the show rather than after it. Afterwards you will be in a crowd, on the move, with no room to study a screen.
