This legendary late-night bar and brasserie has been going through something of a revamp over the last year or so - all in an effort to return it to its art deco roots. Sagely they've kept the walls much the same, still festooned with headshots. Membership is required to gain entry after 9pm but if you've been to the theatre show the guys on the door your stub and, if there's enough room, they'll let you in. And if you really like what's inside? Membership starts at £70 a year.
Keep an eye out for cabaret, musical theatre open mic nights, impromptu performances and more - more often than not from West End casts (they often make a beeline for here). The brasserie serves seasonal British food Tuesday-Saturday evenings, with late-night pizzas available from 9.30pm. There's free wi-fi and portable chargers, too.
