Cafe Hidden is a two-floor private cafe in Mokdong, near Omokgyo, selling cake, madeleines, coffee and ade. It serves a Hidden Shufener and tiramisu, and coats the rims of its drink glasses with sugar. Seating is split across a semi-basement, a first floor and an outdoor area, with a toilet in the semi-basement, and dogs are allowed inside. The space is small, so voices from the next table can be loud and uncomfortable.
