I am a Perthite travelling over to Sydney to meet with some friends I haven't seen for 20 years. They arrive at their hotel in Darling Harbour around 1pm and I'd like to take them somewhere iconic (in terms of views or experience but hopefully not price!) for lunch- but it is Good Friday. Any ideas? I had thought of a trip over to Manly but not sure whether we can get there directly from Darling Harbour. I have a flight to catch that evening. help!
