The standard operating hours for shops should be considered 10a.m.-7p.m., however, in many districts opening hours are much, much longer. In Causeway Bay, Tsim Sha Tsui and Mongkok expect shops to open as late as 10p.m., Wan Chai and Western District shops also operate later hours. Markets in Mongkok and Yau Ma Tei often don’t start operating until 3p.m. or 3p.m. and don’t turn the lights out until 11p.m.
