The tasselled lampshades, mahogany panelling and plush carpet may feel vintage, but this little bar has only been around for a decade – considerably less time than the venerable Rules restaurant below, founded in 1798. No matter; the mood here is precisely what you'd expect of a bar attached to London's longest-running restaurant, with impeccable old-school service and dependable classic cocktails, including the Sazerac and Clover Club. Happily, head bartender Mike Cook is no slave to tradition, so expect modern mixes such as Dick Bradsell's Bramble too, alongside a list of eight signature serves, including the sparkling Normandini (calvados, peach and sparkling Crémant wine) or Eau de Savoja made with rare 1960s Amaro Savoja. There's a knock-out selection of whiskies too, ticking off American rye and bourbon as well as some iconic single malts – great with bar food such as venison carpaccio.
