Childish is a coffee shop in Seongsu, Seoul, that sells salt bread bungeoppang, mango bingsu, and ube bingsu. The mango bingsu contains one whole mango and uses ice with a mango milk flavor. Waiting works by taking a number ticket at the shop, and once a table opens, customers can order takeout. In the salt bread bungeoppang, the sweetness of butter and red bean paste overlaps, making it greasy with weak balance.
