London never seems to get tired. It's perhaps the greatest paradox of a city with a history spanning two millennia that it stays forever young and energetic. Britain's capital is home to the great art collections of the National Gallery, architectural icons such as Tower Bridge, and a rich Royal heritage, but it also spawns underground design and musical innovation. It is a city of independent villages -- for example, Chelsea or Greenwich have little in common with Shoreditch or Soho -- and a conurbation of green spaces as well as great buildings.

Things to Do
The old always sits alongside the new here -- nowhere more so than at Wren's great baroque dome of St. Paul's Cathedral, framed by 21st-century skyscrapers -- and London is rightly famed for its museums and galleries.

Sheekey are as good as ever, and 2011 saw superstar chef Heston Blumenthal reinvent Dinner in Knightsbridge. Areas with lower rents continue to attract skillful chefs to gastropubs, cool cafes, and a new breed of tapas bar.

Nightlife & Entertainment
When darkness falls, the historic monuments and grand museums fade into the inky night, and a whole new London comes to life. The West End's bright lights draw the crowds with long-running mega-musicals and big-name dramas. Less well known is London's growing taste for the offbeat, from cabaret and Charleston revival parties to dubstep, burlesque, and even underground bingo. Soho is still buzzing -- and the streets of Shoreditch, Hoxton, and Dalston are jumping well into the sm
