Nightjar has become a huge success, busy even midweek; we visited on a Monday and were lucky to get in. Clear message: book a table. The cocktail list, divided into historical eras (pre-Prohibition, post-war and so on), makes for enthralling reading with all its unexpected ingredients. Just to give an idea: the Kenko-Teki Swizzle includes green coffee bean infusion, saké, green tea, buckwheat rice syrup and alfalfa. This makes Nightjar a great place for experimenting, as you sit in the moodily lit room with its gorgeous pressed tin ceiling. But if the original drinks are too confusing, you can rely on staff for expert handling of the classics. A couple of small quibbles: the spice level in the own-made bloody mary mix could be toned down; and while the background jazz is fabulous, it probably doesn’t need to be so loud – even if you love Billie Holiday and Louis Armstrong as much as we do.
