Take the MTR or Star Ferry to Kowloon. Shoot pictures of Hong Kong Island. Then go up Nathan road. Notice how crowded the streets are in the Chinese neighbourhoods (midnight is like noon in most cities) and how lots of shops are still open. The tanks of fish in the windows of restaurants are all over the place and can lead to some good photos, esp. if juxtaposed with some of the sidewalk activity. This area is great because all the neon signs are in Chinese (while all the big neon signs just say "Sony" and could be anywhere).
