Lingering over pain au chocolat in a sidewalk café, relaxing after a day of strolling along the Seine and marveling at icons like the Eiffel Tower and the Arc de Triomphe… the perfect Paris experience combines leisure and liveliness with enough time to savor both an exquisite meal and exhibits at the Louvre.

The crown jewels, Buckingham Palace, Camden Market… In London, history collides with art, fashion, food, and good British ale. A perfect day is different for everyone: culture hounds should hit the Tate Modern and the Royal Opera House. Clotheshorses will drool over Oxford Street shops. For foodies, cream tea at Harrod’s or crispy fish from a proper chippy offers classic London flavor. Music and book buffs will freak out over Abbey Road and the Sherlock Holmes Museum (at 221B Baker Street, natch).

Rome can’t be toured in a day, either. The city feels like the exhibit halls of a giant outdoor museum, a real-life collage of piazzas, open-air markets, and mind-boggling historic sites.

Dig into a plate of fresh pasta, some succulent fried artichokes, or a tender oxtail stew for one of the best meals of your life.

Barcelona feels a bit surreal – appropriate, since Salvador Dali spent time here and Spanish Catalan architect Antoni Gaudí designed several of the city’s buildings. Stepping into Gaudí’s Church of the Sacred Family is a bit like falling through the looking glass - a journey that you can continue with a visit to Park Güell. Sip sangria at a sidewalk café in Las Ramblas while watching flamboyant street performers, then create your own moveable feast by floating from tapas bar to tapas bar.

Berlin is an edgy city, from its fashion to its architecture to its charged political history. The Berlin Wall is a sobering reminder of the hyper-charged postwar atmosphere, and yet the graffiti art that now covers its remnants has become symbolic of social progress.
