Shopping destinations:
1. Prices for athletic shoes are quite reasonable in HK and there is a street in Mongkok that has numerous shoes stores.
2. Causeway Bay (CWB) and Tsim Sha Tsui (TST) are great places for shopping and eating. IFC and Landmark in Central for higher-end shopping and eating.
3. After shopping and eating in CWB or TST, there is no reason to go to Tai Koo Shing unless you have a friend living in the area. Same goes for North Point, Hung Hom and Tsun Wan.
4. Nothing interesting in the Western District unless you need to buy dried abalone, mushroom, birds nest or sharks fin
Interesting destinations:
1. Watering holes are located in Wan Chai, TST and Lan Kwai Fong in Central. Take the long escalator ride from Central up to Mid-Levels. It cuts through Soho, another popular area for food and drinks.
2. Lantau Island has the Big Buddha statue. Take the cable car ride up to the top. You can pay a few dollars for a Crystal Cable car with a glass bottom. The view of the HK Airport is quite impressive too.

3. Non-tourist destination: Car dealerships (including Porsche, Land Rover, Jaguar, Lamborghini, BMW and Maserati) are located on Gloucester Road. Free feel to walk into a dealership and look at the cars. There is a Lamboghini exhibition at the ground floor of Soundview Plaza 2, a new commercial building next to Times Square in CWB.
Enjoy the city. By luck, we may cross path in HK!
