Chinatown, in San Francisco, California, is the oldest Chinatown in North America and the largest Chinese community outside Asia. Since its establishment in 1848, it has been highly important and influential in the history and culture of ethnic Chinese immigrants in North America. Chinatown is an enclave that continues to retain its own customs, languages, places of worship, social clubs, and identity. There are two hospitals, numerous parks and squares, a post office, and other infrastructure. Visitors can easily become immersed in a microcosmic Asian world, filled with herbal shops, temples, pagoda roofs and dragon parades. In addition to being a starting point and home for thousands of Chinese immigrants, it is also a major tourist attraction, drawing more visitors annually than the Golden Gate Bridge. About the roast duck.... Okay, I'm biased, but San Francisco Chinatown has the BEST roast duck...EVER! From Cheung Hing (Outer Sunset) to Win's Restaurant (Parkside). It's just to die for. Best eaten with hands. :)
