If you're in Sydney city, I'd give 42g a miss. Way out there out of the way with practically no public transport (buses, hah!), such a hassle to get to unless you drive. Top choices are the Ginzas for FS, CDB Style for "massage", and SBM/SGM in Darlinghurst/Woolloomooloo for massage. You're gonna have a full plate just from those.
