Yudong Coffee Salt Factory is a coffee shop in Yongdam-dong, Jeju City, converted from an old salt factory near Jeju Airport. It serves specialty bean americanos, salt milk latte, and salt bread, and the salt milk latte is drunk by melting an espresso cube. The store is small, so you take a seat before ordering, and the salt bread can sell out by noon. There is no parking lot, and the spacing inside the store is narrow.
