唐人街欢迎您！
旧金山的唐人街在全美规模最大、历史最为悠久，是一个非常受欢迎的旅游景点，每年接待的游客甚至比金门桥还多。这里一年四季气候温和，这意味着任何时候都适宜来游览。
历史上，在修筑铁路和淘金热时期，来自中国的移民定居于此。早先作为中国移民的住宅区的地方后来变成了中国文化的中心。如今唐人街的绝大多数居民依旧是华人，他们中很多人英语说得并不流利。这能让游客体验到正宗的中国味。
唐人街的大部分建筑毁于1906年的大地震，但是市政府和居民将它重建，并且特地融入诸多中国建筑元素。传统上，游客从具有传奇色彩的龙门走入唐人街，龙门的建筑材料是由中国捐赠的。其他的著名景点还有天后古庙、广东银行等，不胜枚举。游客亦可花上数小时，一探此地的中国味道与美景声色。作为唐人街的中心，花园角广场也是一个重要景点。广场历史悠久，声名远扬，作家罗伯特·路易斯·斯蒂文森曾长居于此进行创作。如今，花园角广场已经成为游客的一个好去处，在那里可以欣赏现实生活里的中国传统文化，如中国象棋和练太极拳。
唐人街的商店出售各式特色纪念品、货物和衣服。各种各样的中草药也随处可见，还有中国茶叶商店，在那里游客可以品尝和购买各种中国茶叶。
然而，很多游客和旧金山人最钟爱的或许是唐人街的美食。这里有着来自中国各地的传统菜肴，各种口味，应有尽有。
唐人街是美国多元文化的一个重要组成部分。未曾踏足中国的游客可以在唐人街近距离感受中国传统文化。
