943 King's Cross 홍대 카페 943 킹스크로스

Every floor from the basement up to the fourth recreates a different corner of Hogwarts. Early weekday hours are the quietest time to look around the props. Admission covers one drink, and the rest of the visit works like a light escape room: hidden clues on each level lead to small missions and a sticker collection. The basement is kept dark, which some young children find frightening.
