Charles H is an upscale speakeasy hidden behind an unmarked door in the basement of the Four Seasons Hotel Seoul. Its decor evokes the Prohibition era with an Art Deco facade, gorgeous polished marble, a backlit bar, and grained leather booths. The carefully crafted menu reads like a guidebook. The bar's name is a tribute to Charles H. Baker, explorer, author of The Gentleman's Companion, connoisseur, and one of the world's pioneering bartenders.
