"Open for: Dinner until late night Price range: $$$ Charles H is a speakeasy discreetly hidden away in the lower level of the Four Seasons Hotel Seoul. After passing through a secret passage, guests find a glamorous interior suited for a lux hotel bar with decor inspired by Korea’s traditional metal ornaments. The cocktail list contains classics and original creations inspired by Charles H. Baker, the eponymous bon vivant who wrote the classic cocktail book The Gentleman’s Companion. Know before you go: If you’re staying at the Four Seasons, you don’t have to pay the cover charge." - Matty Kim
