There are a few pins in Sydney CBD,
Windsor hotel has TZ, NF and RS
The James Squire on King Street wharf has Stern Indy Jones & t2 - good beer too brewed on premesis
The sports bar in Menzies hotel has STTNG, IJ and SS
but the best place to go would be Newtown which is just 2km from CBD which has nice pubs with pins
eg Court House hotel - Spiderman, TZ, AF, JY, Congo - and good place for a feed too
& walking distance from Courthouse is the Sandringham hotel with MM & IJ

There is a sticky on this web site which is a database of pin locations - can't find it right now but if you look around you'll find it
