Wave On Coffee is a three-story cafe in Gijang, Busan, overlooking Imrang Beach. It serves Brazil Campo coffee, whole wheat lattes, and passion fruit ade, which you drink from seats facing the sea. Entry requires one order per person, and there is a bungalow-style annex with outdoor beanbags and sea windows. On weekends it gets crowded and it is hard to find a seat, and the space is cluttered.
