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.
Per 100 g, the cheapest chips are KFC's Large Chips (240 g for a median $5.95, or $2.48 per 100 g). The dearest are McDonald's's Large Fries (128 g for $5.20, or $4.06 per 100 g).
Each brand's best value size, per 100 g: KFC $2.48, Hungry Jack's $2.92, Nando's $2.99, Oporto $3.00, Grill'd $3.05, Guzman y Gomez $3.08, Red Rooster $3.26, McDonald's $4.06.
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.

Fries Watch divides each size's median pickup price across a brand's restaurants on 2 October 2026 by the serving weight the brand publishes, and takes each brand's best value size. Only brands that publish weights are included. Prices are in Australian dollars and are not converted; only chips are compared between brands, never baskets.
