Centro is smack dab in the heart of Oakleigh which is predominantly a Greek district. The food shopping offering reflects this well. Apart from quite a few great food shops including a bakery, deli, fruit and veg, a few takeaways you also have two supermarkets in the complex. Woolworths and Coles. Personally I prefer Coles. There's more on offer and more varieties of everything. I'm bad at comparing prices so can't tell you which is better in that respect but Coles does seem more popular generally.
There a good parking garage under the centre although sometimes, like on weekends it seems quite dimly lite (saving money??) which makes it feel a little unsafe. But maybe that's just me.
Also a very easy walk from Oakleigh railway station.
It does get busy here on a Saturday morning. If you have time it's also worth stepping out of The centre into Portman street. You'll find heaps of butchers and fishmongers and plenty of other things to keep you occupied. read more
