Taitung Tourism Night Market takes over Zhengqi Road on Thursday, Friday, and Saturday nights. By day the area is tied to fruit trading; after dark it shifts into snack stalls, simple games, and the kind of easy street food grazing that works well in a smaller Taiwanese city.
It is not as vast as Taiwan's famous west-coast night markets, and that is part of the appeal. Come hungry, then wander toward Fantasy Tiehua if you still want lights and people afterward.
