Oporto
Hands down, the best fast food in the Sydney Airport is Oporto’s Portuguese chicken Bondi burger in a chile piri-piri sauce with ginger, lemon, and garlic. The Oporto franchise, which began with a single grilled chicken joint in Sydney’s North Bondi neighborhood and now has more than 100 locations across the country, is the Aussie version of the Golden Arches—but so, so much better.
