Imperial Cocktail Bar is located within the kitschy Imperial hotel. It is considered one of the top 5 bars in the world. The bartenders are superb and will improve clever drinks.
The food consists of small plates and the hosts are aggressive in turning over the very small bar and table area.
Absolutely make a reservation and ideally go with a date.
This is a great place to meet someone for drinks and, before you know it, the date will reach a natural conclusion courtesy of the polite, but firm staff.
