I think the food is probably fine just so long as you're not Australian. The meat isn't right, the pastry isn't right and the sausage rolls just made me cry on all counts. Oh and the prices? Just as well you're in old town and targeting tourists because those prices are ridiculously high.
All I bought were meat pies and sausage rolls. So maybe other things are nice but they are not a good representation of an Aussie staple.
If you've never eaten a real Aussie pie then you'll probably think these are okay. If you're Australian take a pass. Either make your own or wait till you get home. If you want authentic don't buy pies from here. Save your money, fly to Australia and have a great pie.
