The experience at Chachai Tea begins with exploring desserts paired with tea in a small space located opposite Caramellio. This area serves as the welcoming space where customers are greeted, and it acts as the entryway to the tea house located one floor above. After receiving guidance here, guests go up a floor to reach the tea room. The tea room is designed with a counter format, and the Hanji paper used on the walls is specially processed to create a deep, dark expression. However, the copper metal materials used in the space add warmth. To alleviate the sense of confinement in the low-ceilinged space, a fabric wall installed along the side walls features integrated lighting design.
