Bar in London

The 1893 hotel bar that wrote the cocktail manual the rest of London still reads

Mr Lyan's South Bank flagship, the first 3-PIN bar in the Pinnacle Guide, Thames at the window

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.
