Time Out says
The Keio Plaza's flagship bar offers a fine lineup of domestic spirits, with whisky particularly well represented. Their fun 'keep a bottle' service allows patrons to have unfinished bottles stored under their name, cutting the price of individual glasses to mineral water-level. Try it out if you plan on staying for a while or visit the area regularly.
