Hiroyasu Kayama is both scientist and bartender at this bar on the ninth floor of an office building. Kayama has a collection of dried herbs, spices, and even bugs on the shelves behind the bar. The best seats are at the counter, where you can watch as Kayama creates from scratch a Campari using cochineal insects. To witness the red color come to life gets your mouth wet for the drink that awaits. The absinthe made with wormwood should also be on your radar. Best to tell Kayama what cocktails you like and let him recommend something for you.
