Concierge.com's insider take:
In the 1930s, Shanghai was covered with blocks of shikumen (traditional stone-gated structures). Today, most of these narrow middle-class houses, which typically featured five rooms upstairs and down, have been destroyed to make room for glitzy high-rise buildings. Xintiandi is a preserved neighborhood—one of the city's best (and only) examples of old Shanghai architecture—now transformed into an upscale mall, boasting a collection of swank restaurants, bars, and shops. For a glimpse into the life of a typical 1920s middle-class family, don't miss the Shikumen Museum, formerly a residential property that has been restored to its former charm and decorated with artifacts found in nearby houses (25 Lane 181, Taicang Lu; 86-21-3307-0337). Wash the taste of capitalism from your mouth with a visit to the nearby Museum of the First National Congress of the Chinese Communist Party, which pays homage to the party's 1921 founding with a wax tableau of the first meeting and a brief tour of the humble brick lane house where it all started (374 Huangpi Nan Lu, by Xingye Lu; 86-21-5383-2171).
