The Altivo 
I've been there on several occasions.
Say if you're going with a date - a good idea would be cable car
ride from Harbour Front to Mount Faber - then walk a few steps
right up to the place (Call in advance to make a reservation at the
cushion seat if possible)
Price wise - it depends on whether you're planning to dine or
just going for drinks. If you're dining and not having
any wine, you'd be looking at around 50 - 80 per person, top
it up with a few beer and cocktails to wash down the food... (I
don't know bout you, but I'm quite a big drinker) Total bill can
hit up to 200.
But if you're conventional-no-nonsense-not-too-many-drinks kinda
person, then a safe estimate would be around $100.
P.S. Place is pretty inaccessible, you really don't want to be
stucked at the top of the hill with no vehicle... So 1) Either have
your own ride 2) Borrow your folks' ride 3) Be in time for the last
cable car ride <-- Can't remember what time though
$100 per person or for both?
thanks alot for your info! =D
