MissS13: are you talking about "the summit"? coz 41 doesn't spin around?
41 is nice. i think its an experience everyone should have, if they can, but i wouldn't go back there. foods really nice, imho, the atmosphere is too "intense" though. i'd rather a more relaxed atmosphere.
bel mondo's is as good as 41 in terms of service and food but its a much more relaxed atmosphere (obviously hasnt got the same views as 41 though)
Drivebai: the "panorama" on mt keira? yeah, have to admit great atmosphere and food, its like your sitting in an italian mansion. and then of course the drive down to the beach after dinner for romancing
if you like your steak, id give Prime a go under the Westin Hotel in Pitt St. really up class but no view. If your on a smaller steak budget the Kingsley on King St is the place to be.
Personally i think all of the above are too cliche for valentines, try and be original!!!
