Qianmen, which means "front gate," ranks among the top tourist sites in Beijing. It stands south of Tiananmen Square and serves as the marker for a shopping street, refurbished ahead of the 2008 Olympic Games (to mixed reviews). The major point is that this area packs them in due to a nearly 600-year history, and its and proximity to major attractions.
One luxurious stop after pounding pavement in that area is Capital M, considered among Beijing's top restaurants. It has a reputation for everything from its food and service to its annual literary festival, but what is especially of interest to visitors is the third-story terrace that looks toward Qianmen, Tiananmen, the original Beijing Rail Station, and other key landmarks.
This is the spot for afternoon tea, with tiny sandwiches, scones, jams, and more. Or, if you visit on the weekend, go for brunch. That usually goes three courses, starts with a Bloody Mary or Mimosa, and typically ends with the restaurant's best-known dessert, pavlova.
You'll be inspired to walk another three or four hours to work off those calories.
