If you're after a quieter food court in the weekends, Pitt St may be the one for you. We went here recently on a Saturday evening and found it to be quiet and not too busy. There was a reasonable selection of food stalls to choose from. Our group of six went to a few different stalls. All of our food was fine. None of the servings were huge, but they were all adequate. They had a very efficient cleaner who kept the tables and seating area clean and tidy.
I went to Pitt Street food court as I had a Grab One voucher to use and it was surprisingly good. I have been back a couple times since and it really has some delicious food options. The atmosphere is one of the best parts, they have a great outside area which has been well heated so we have sat out their on various occasions. Also the alcohol is incredibly cheap.
