Port Willunga hosts the justifiably busy, clifftop seafood shack the Star of Greece. Named after a shipwreck, it has funky decor, great staff and a sunny patio. We asked the waiter where the whiting was caught: he gazed across the bay and said, ‘See that boat out there?’ There's also a takeaway kiosk (snacks $7 to $15, open weekends and school holidays).
