I just moved here from NYC and, being somewhat used to high-cost living over there, am still shocked at some of the prices in HK:
- rent can be cheaper and more spacious if you live farther from central - which is what we opted for...
- cell service - beware, lots of little tiny added charges and the contract seems much more complicated than the states - especially data-services. in the states almost all packages are unlimited data but here, you can also be charged by kb's - which is a pain. Also, if you're used to 'no roaming charge' or 'free nights and weekends' - they don't really have it here. in a nutshell, check your bill every month to make sure you're paying what you should be paying...
- i would just forget starbucks, a tall iced coffee is actually MORE expensive than New York!! Although you have other choices like Pacific Coffee etc - they are just as $$$. I suggest make your own coffee at home. :-) Although the coffee beans / grinds (illy / starbucks) are not really that much more than the states... i think HK people think drinking coffee as the 'experience' of sitting and enjoying their coffee in a nice atmosphere, not like the U.S. where we grab our starbucks and run, downing the thing like there's no tomorrow -ie. human gas stations...
- food can be cheap if you know where to go. We were introduced and kinda addicted to the 'semi-fastfood' joints like Cafe DeCoral and Maxim Mix. Also the foodcourts here are NICE, (again the ambience is important to HKers) compared to the typical mall-fare in the states... so no worries there. cheaper to eat out than cook at home - although still trying to spot a decent pizza joint (help someone??)
- TV, similar to cell service. Channels are a la carte - you only pay for channels you want - which is good in theory but for someone like me, it seems (psychologically) more when you actually need to choose the channels - since they are $$/month. But all in all i guess it's cheaper. also no such thing as DVR so it means you either watch the show at the scheduled time or you miss it... hard concept to grasp again... adding to the feeling that you're not getting your $$$'s worth (if you don't get to watch everything you wanna watch)
- Furniture - you'll likely have to buy it here since the apts (and the elevators) are small. We ordered a queen size mattress from ikea and they almost couldn't get it up the elevator - i was shocked. and the apt ain't small... wonder how people actually furnish their place... dreading our furniture currently being shipped here.
