Beef soup (牛肉湯, niúròu tāng), a Tainan speciality, is served as early as 4am for breakfast, right after the cattle are slaughtered. One of the best places to savour the soup and the meat at its freshest is A Cun, a street-side stall that has been feeding late-night revellers and early risers for more than four decades.
From Tainan Train Station, take bus 6 (bound for Longgang Elementary School, 龍岡國小) and get off at Baoan Temple (保安宮). Walk towards where you came from and turn right at Guohua St, Section 2 (國華街二段). The shop is at the junction of Baoan Rd (保安路) and Guohua St (國華街).
