핵심 사실

Fast food chains are collecting more and more data about their customers through mobile apps and loyalty programmes: accounts with their details, and what they order and when. They are also experimenting with AI and data-driven pricing. Meanwhile the same item can cost very different amounts from one restaurant to the next, and customers cannot see why. Drive Thru Index publishes every restaurant's real price, every day, so anyone can check.
Hungry Jack's: a Whopper costs $9.40 at two Hungry Jack's restaurants in Fulham and Gawler, SA and $10.80 at the Hungry Jack's in Mt Barker, SA, $1.40 (15%) more. Across its 40 restaurants in Greater Adelaide, the median is $9.90, the same as Hungry Jack's Australian median of $9.90.
McDonald's: a Big Mac costs $7.85 at the McDonald's in Trinity Gardens, SA and $8.95 at three McDonald's restaurants in Mount Barker and Frewville, SA, $1.10 (14%) more. Across its 56 restaurants in Greater Adelaide, the median is $8.45, the same as McDonald's Australian median of $8.45. At the airport in Adelaide, SA, it costs $9.20.
Anthony Gherghetta, an Australian software developer who built Drive Thru Index, started it after reading some of the buzz about AI being used to set fast food prices: he wanted to see whether it was true, and how big the price differences between restaurants really were. Prices bear out the contrast he noticed. In Australia, 97% of McDonald's restaurants charge within 10% of the typical Big Mac price; in the US, 53% do. The gap between the cheapest and the dearest tenth of restaurants is 10% of the typical price in Australia and 33% in the US.
“I kept reading that fast food chains were starting to use AI and customer data to set prices, so I wanted to see if it was true and how big the differences really were. In Australia, where I’m from, a Big Mac costs much the same wherever you buy it. In the US the price changes from one restaurant to the next. Fast food apps now know what you order, when and where, but customers can’t see how prices are set. So I built Drive Thru Index to check every restaurant, every day,” said Gherghetta.

Drive Thru Index reads every restaurant's menu from each chain's own ordering app every day; these are the latest pickup prices collected on or before 1 October 2026, in Australian dollars. The area covers restaurants within 40 km of the city centre of Adelaide, each restaurant counted in its nearest city. Each chain is compared only with itself, on its own signature item, and only where it has at least 5 restaurants in the area; prices are never compared between chains or converted between currencies. The cheapest and dearest restaurants leave out airports and similar special sites, which are reported separately.
