Parra campus sells it at the bar and the food tends to be pretty similar across different campuses..
although - there's plenty of better value stuff lol - eg cafe at parra sells full like.. sit down meals at around $8-10... meanwhile peopel are buying chips n burgers at the bar which don't taste as good and aren't healthy lol for the same cost
i don't think you can get sushi on campus just yet.. but the canteen menu is changed regualarly so you never know... there some shops about 5mins down the road, i really haven't gone to them but you could have a look one day.
I wish Blacktown had Sushi. Maybe they do though, and I just dont know it. I would probably be in the Cafe if they had it becuase thats where they have all the yummy foods.
i get a feeling all the food places will be updated soon since parra's being/been done and they seem to try to make stuff similar across campuses... so maybe you guys will get updated too and have more stuff to choose from?
