This swank and sophisticated little salon – think red velvet banquettes, round, low tables and shelves of books – has a unique cocktail focus: tea and traditional Chinese medicine. For example: its version of a sidecar is made with aged roasted tea, cinnamon and ginger (the latter two considered to fortifying properties). And if you just want tea, they serve that, too.
Ao is inside the new (opened in 2020) boutique hotel K5; it's unmarked (speakeasy-style) but the front desk staff will show you the way. Cocktails from ¥1540 plus 10% service charge..
