💡 Secret Travel Tip: Passing Through the Ticket Gates

Some of these hidden cafeterias are physically located inside the ticket turnstiles. If you are not planning to ride the subway but just want to access the cafeteria, do not tap your transit card and pay a fare!

Simply follow these steps to pass like a local:

Walk up to the handicap access gate or the side turnstile.
Press the silver "Help" (도움벨) button on the gate.
When the station staff answers via the intercom, politely state your purpose in Korean: "식사하러 왔어요." (Sik-sa-ha-reo wass-eo-yo) — I am here to have a meal.
The staff will happily buzz the gate open for you. When you leave after eating, simply press the button again to exit without any accidental transit charges.
