If Breakfast At Tiffany’s had been set in present-day London, Holly Golightly would likely be ‘slumming it, darling’ with her boho playmates at this semi-secret jazz joint. Squirrelled away behind the black door of a narrow Soho townhouse, The Piano Bar occupies a small but smart cappuccino-tone drawing room that’s available to hire for functions during the day. By night it morphs into a live late lounge serving wine, bubbles and cocktails: Long Island Iced Tea, Old Fashioned, Manhattan, Twinkle, Bramble (all at £9.50) and various other classic NY-Lon numbers. The guest musicians certainly cut the mustard. Here’s where to discover a latter-day Chet Baker or Tony Bennett and foxy dames in the tradition of Billie, Ella, and Amy Winehouse at her most sultry. The venue is nominally a private club (the annual fee is around £100), but non-members are admitted by advance online booking – so plan ahead.
