Hong Kong is real fun!
A great place with great food and shopping experience! Lots of things to see as well with numerous museums and nice scenery. I personally recommend The Peak and Stanley Beach, they are simply spectacular. For shopping, I would recommend Causeway Bay.
Insider Tip:Learn some Cantonese. If you can speak some Cantonese, it would be much easier to move around especially when communicating with older folks. If not, most people could speak Mandarin and for younger people, they could speak English as well.
