"Grandma's Little Bakery" looks like a misnomer to me. It should probably be called Ia-ia's or Nonna's or Siti's. This cafe, function centre and shop is located in the Fedra olive grove, just off the Federal Highway in the Collector region. They specialise in olives, of course, and other Mediterranean products, and they serve meals as well as selling foods. They seem to be doing pretty well - we dropped in on our way back from Sydney last week and the place was packed.
The shop is quite the treasure trove. You can find freshly made hummus, pestos, olive and ricotta dip, tapenade, and more. There's a range of home made nougats - the pistachio and apricot is great - and other confectionery. There's ingredients such as syrups of rose, date, and pomegranate, dry goods such as lentils and couscous, and a big range of spices, whole and ground including exotics like za'atar and baharat. But the spice tub sizes are a bit too large for me; they'd be stale by the time I finished. You can buy their specialty boreks packed frozen to take home. There's also fresh baked bread, bagels and pastries, and they stock the well-known Lynwood farm preserves.
We didn't actually stop for lunch or arvo tea, since we'd just had a big brunch in Sydney. But having checked the place out and enjoyed their produce, I hope to make it a destination sometime.
