Glass and concrete best describes the Financial District, a compact area of skyscrapers reaching dizzying heights and home to Canada's business capital. 27 km (16 miles) of underground interconnected passageways called the PATH, feature 1,200 retail stores and services. Next to the Financial District is Canada's Entertainment Capital which offers a high concentration of clubs, bars, theatres, restaurants, sporting venues and retail shops located in the vibrant setting of the city's core. Each of the streets in the Entertainment District has its own flavour, and its own specialty. For example, Queen St. West is a funky retail street, King St. West is lined with theatres, broadway, concert halls and a wide array of restaurants. Richmond and Adelaide Streets are home to massive, 3-storey nightclubs and smaller, high-end restaurants. Front St. West features the SkyDome, CN Tower, and Air Canada Centre which brings huge crowds for sporting events or musical concerts.
