Twosome Place Haeundae Sumokwon is a cafe near Haeundae Arboretum in Busan that sells coffee, drinks, and cakes. The two-floor space has wide spacing between tables and a separate study zone. It stays open until 11 p.m. and offers free underground parking, and it is quiet on weekdays. The underground parking entrance is narrow and materials are stacked on the second basement floor, which makes parking inconvenient.
