I'm from Hong Kong!

Yay! Another Hong Kong tourist. :)

Firstly (and most importantly, of course), there is a gadget heaven in a shopping district called Mong Kok (yes, feel free to giggle; http://en.wikipedia.org/wiki/Mong_Kok ), a street called Sai Yeung Choi Street: http://en.wikipedia.org/wiki/Sai_Yeung_Choi_Street

All the big shops there are legit and quite competitive, so don't forget to haggle!

Hotel-wise I don't know what your budget is, but the one that I usually put my clients in is the Royal Plaza Hotel, which is also in Mong Kok and is above a great shopping mall: http://www.royalplaza.com.hk/

If you're looking for a budget hotel, the Shamrock Hotel in Jordan (near Tsim Sha Tsui - another shopping heaven; http://en.wikipedia.org/wiki/Tsim_Sha_Tsui

) would be a good choice: http://www.shamrockhotel.com.hk/en/index.html

Obviously you should try to book via travel agents, which will make it a lot cheaper.

Restaurant: if you can read Chinese, there's a fantastic online guide for HK restaurants. I've personally picked three, one of which I have been to before (the second one):

Super Star Seafood Restaurant 鴻星海鮮酒家:

They are all in the Tsim Sha Tsui district - just an 8-minute underground train (we call it the MTR) journey from Mong Kok, and it is another shopping heaven. However, don't bother visiting those so-called "tax free" electronics shops, as we don't have value-added tax anyway plus they have many scamming tricks up their sleeves, just for tourists.

The buffet restaurant in the hotel is also very nice, and I think they do afternoon discounts which would be great for your family.
