Bar in London

Frith Street's 1959 jazz room, the canonical London jazz club, two sets a night, low ceiling, red lamps

Agostino Perrone's silver-trolley martini and a room that has spent a decade at or near the top of the World's 50 Best Bars list.

Hoxton Square's basement, the small, no-fuss cocktail room the trade has booked since 2010

Two-floor Old Compton Street cocktail room, aperitivo bar upstairs, three-hundred-whisky lounge below
