The entrance to this glamorous bar is behind a doorway hidden between two cafes on the fringes of Shoreditch, so you'll need to do your homework even to find the place. You are seated at a table and served cocktails that range from pre-Prohibition to modern. Nightjar is open seven days a week. There's vintage jazz from Wednesday through Saturday, when there's a cover charge of 5 pounds to 7 pounds. Reservations are highly recommended.
Signature drink: New Orleans Fizz (12 pounds).
