I think it varies from place to place. In the larger cities I've lived in, they're more like corner stores, but when I lived in rural NSW, the local milk bar was also the fish and chips shop, and it also sold dim sims and chicken schnitzel and that sort of thing. I was going to say cafe originally, but where I am at the moment (Townsville, North Queensland), a cafe is a coffee shop/tea house and not all of them also have a decent meal selection.
