We caught the lift at Circular Quay up to the Cahill Expressway and walked from there across the bridge to the Kirrabillie Markets.  Hundreds of stalls but we didn't buy anything but lunch.  There's a great view from the park under the bridge and then walking around to Luna Park where we caught a ferry to Darling Harbour.  A coffee for John and a chocolate milkshake for me from Lindt, finished off a lovely day.
