Rumpus Room, SE1

The Rumpus Room has got to be the most glamorous rooftop bar in London. On the 12th floor of the South Bank’s ultra-chic Mondrian hotel, it evokes the glitz and excitement of 1920s London: think blood-red banquettes and glittering dandelion chandeliers, jazz and laconic barmen mixing up the driest of martinis. Step out onto the terrace for dazzling views up and down the Thames.

The view: Stunning 360° riverside panorama, with all of London’s best buildings lining up to be admired.
