Atteu 9 is a cafe on the third and fourth floors in front of Namhangjin Beach in Gangneung. It serves coffee with acidity and tomato juice ground on site, and orders are placed on the third floor. Seating is plentiful on the third and fourth floors, and the 360-degree view takes in the sea, sky, and mountains together. When it is crowded, sound echoes inside and makes conversation difficult.
