Try to drop by Ocean Terminal and Harbour City. That's where the hi-fi stores are. There's another 9-storey building which houses most of hi-fi brands on all nine levels?! Unfortunately, I do not know the name. Will let you know if I find out the building and street name. Food are aplenty and cheap. Just do not order soft drinks by the cup. Order it canned especially if you are in those eateries along the road. That's a small street called Lam Kua Fong where all the happening pubs, bars and jazz clubs are. You can't miss it. Peak is worth a visit at night.
Cheerio!
Cheerio!
