Tai Kok Tsui is an area west of Mong Kok in Kowloon, Hong Kong. The mixed land use of industrial and residential is present in the old area. The Cosmopolitan Dock and oil depots were previously located there. Blocks of high-rise residential buildings have been erected on the reclaimed area to the west, which marked the revitalisation of the area with many restaurants and bars setting up shop. Many of the older residential buildings have been vacated and are set to be replaced by high-rise residential and commercial buildings.
