As an Australian who's been away from home for over a year now Ta Pies was just what I needed to curb some of the home sickness. I have been back a few times now with my girlfriend who is French-Canadian and she is hooked as well. I think their traditional mince pie is my favourite, but we have sampled quite quite a few of their selection now and they were all delicious.
I can say with confidence Ta pies are definitely on the mark with quality and taste. They are equal if not better to a lot of really well known bakeries from my home town in Tasmania.
They also have a number of Australian lollies/treats for sale including curly wurlys (my favourite as a kid) Anzac Cookies, Lamingtons, Milo etc.
This place is great if you are also in a hurry or need something for dinner later as you can buy refrigerated pies in different sizes to warm up at home.
