The metropolitan area has one of the most diverse Chinese-speaking communities with several varieties of Chinese being represented. Metro Vancouver contains the second-largest Chinatown in North America (after San Francisco's), and many multicultural neighbourhoods such as the Punjabi Market, Greektown, and Japantown. Commercial Drive, the core of the historic Little Italy, which is also the main Portuguese area, has become an alternative-culture focus, though traditional Italian and Portuguese and other establishments and residents remain in the area. Bilingual street signs can be seen in Chinatown and the Punjabi Market, and commercial signs in a wide array of languages can be seen all over the metropolitan area.
