Kong Cafe is in the central area north of Hoan Kiem Lake, selling coconut coffee and salt coffee. The interior uses khaki colors, military-style uniforms, army canteens and old photographs for a socialist theme, and the second-floor terrace looks out over the lake and the sunset. Order at the first-floor counter, take a buzzer, pick up your drink on the second floor and sit on the second or third floor. The stairs are narrow and steep, making them difficult to move on.
