Avenue U is a street located in Brooklyn, New York City, United States. This avenue is a main thoroughfare throughout its length. Avenue U begins at Stillwell Avenue in Gravesend and ends at Bergen Avenue in Bergen Beach, while serving the other Brooklyn neighborhoods of Homecrest, Sheepshead Bay, Marine Park, and Mill Basin along its route.
Avenue U in Homecrest now supports southern Brooklyn's second Chinatown (唐人街, U大道), as evidenced by the rapidly growing number of Chinese food markets, bakeries, restaurants, beauty and nail salons, and computer and consumer electronics dealers between Coney Island Avenue and Ocean Avenue. Since 2004, the Q train on the BMT Brighton Line goes to Canal Street in the Manhattan Chinatown (紐約華埠) to Brooklyn's Avenue U Chinatown directly. (The area was formerly served by M, and D trains, which did go to Manhattan's Chinatown, albeit at different times at different stations, Canal Street on the M Train, Grand Street on the D Train) A third Chinatown has subsequently emerged in southern Brooklyn, in Bensonhurst (唐人街, 本森社区), served by the D train.
