The first rule here is to purchase a bottle of whiskey. There is a wide range of whiskies available, from reasonably priced ones such as "Suntory Kakubin" and "Old" to high-end ones such as "Yamazaki" and "The Macallan," and they can even prepare them according to your requests. A female staff member, commonly known as "Koyuki-san," stands at the store on a daily basis and makes highballs in front of you, allowing you to enjoy the taste while conversing with her.

The second floor is a Western-style room with chic sofas for relaxing. You can enjoy a quiet whiskey in the atmosphere of a true hideout. In addition to light meals such as fried chicken, shaomai (steamed pork dumplings), and potato salad, Yuasa Kaikan also offers delivery of dishes from other restaurants.
