Mixology Boutique is a small shop and bar selling whisky and Japanese liqueurs, located in a commercial facility under the train tracks near Shimbashi Station. It stocks hard-to-find bottles including Japanese whisky, single malts, Michters, Hazelburn, and Yamazaki, and you can taste them at the bar while hearing about them. Staff explain the characteristics of each drink in detail, and bottles come with duty-free application and careful takeout. The shop itself is small.
