Konhas is a roastery cafe in a converted three-story house in the Hannam residential area. It serves flat whites, espresso drinks, and desserts such as bakery items, cakes, and pudding. Customers can choose from eight kinds of beans for a brewed coffee, and there is a small pool on the terrace and in the garden. The cafe draws a crowd on weekends and on weekday afternoons, so seats fill up quickly.
