Since 2017, a small cafe in South Korea with their creative interior design has been transporting its visitors to a two-dimensional world. Cafe Yeonnam-dong 239-20 in Seoul features all-white walls, floors, furniture, and fixtures accented with black contour lines that give the space the flattened look of a cartoon drawing. Illustration-inspired elements include drawn cacti, a curious puppy, and blank picture frames. Some of the beverage containers even sport defining lines.
