Downtown and its tunnels
The business district alternates glass towers, theatres and plazas. Beneath the streets, a network of air-conditioned tunnels about 10 km long links nearly a hundred blocks, with restaurants and shops, open only on weekdays during office hours. Discovery Green, a 5-hectare park opened in 2008, livens up the area with concerts and markets. The Theater District, one of the densest in the country, hosts opera, ballet and the symphony. In the evening and at weekends downtown empties: keep it for half a day and a show rather than as a base.
