Mailroom Sindang is a cafe near Sindang Station and Sindangdong Jungang Market that serves coffee and espresso drinks. The menu includes Ethiopian bean cold brew, matcha latte, and salt egg tart, and in the evening it turns into a cocktail bar. Customers write their order on paper and hand it in, then use the standing seats on the first floor or the seating on the second and third floors, picking up their drinks themselves at Mailroom. There are few seats, so people go up and down floors looking for a place to sit.
