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.
Across its 2,133 restaurants, Greggs' Sausage Roll costs from £1.35 (1907 restaurants) to £1.70 (108 restaurants): the dearest charges 26% more than the cheapest, and 89% charge the typical £1.35. The same basket of five items costs from £10.95 to £13.70, a spread of 25%.
Across its 1,338 restaurants, Domino's Original Cheese & Tomato (medium) costs from £14.99 (14 restaurants) to £22.99 (18 restaurants): the dearest charges 53% more than the cheapest, and 41% charge the typical £19.99. The same basket of four items costs from £39.32 to £55.61, a spread of 41%.
Across its 898 restaurants, KFC's Zinger Burger costs from £5.99 (791 restaurants) to £6.99 (51 restaurants): the dearest charges 17% more than the cheapest, and 88% charge the typical £5.99. The same basket of five items costs from £19.85 to £23.25, a spread of 17%.
Across its 596 restaurants, McDonald's Big Mac costs from £4.79 (2 restaurants) to £6.29 (4 restaurants): the dearest charges 31% more than the cheapest, and 19% charge the typical £5.49. The same basket of five items costs from £19.85 to £25.05, a spread of 26%.
Every one of Nando's 486 restaurants charges £5.95 for the 1/4 Chicken. The same basket of four items costs from £22.15 to £22.40, a spread of 1%.
Across its 359 restaurants, Pizza Hut's Margherita (large, handcrafted) costs from £19.49 (304 restaurants) to £25.98 (55 restaurants): the dearest charges 33% more than the cheapest, and 85% charge the typical £19.49. The same basket of four items costs from £32.46 to £39.25, a spread of 21%.
In the US, by contrast, the dearest ordinary McDonald's charges 125% more for a Big Mac than the cheapest, across 13,657 restaurants. Only the percentages are compared: prices are never converted between currencies.
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. In the UK, 94% of McDonald's locations, the biggest chain tracked there, charge within 10% of its typical Big Mac price.
“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.

Méthodologie, à propos et contact
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 12 October 2026, in pounds sterling. A chain's spread is how much more its dearest restaurant charges than its cheapest, as a share of the cheapest price, for its signature item and for the same basket of items; chains with fewer than 5 restaurants priced are left out. Airports, stadiums and similar sites are left out, and so are prices below 40% or above 250% of a chain's typical price, which are almost always menu errors. Each chain is compared only with itself, and another country is compared by percentages alone: prices are never converted between currencies.
About Drive Thru Index: Drive Thru Index (drivethruindex.com) publishes the menu price of every item at every restaurant of the biggest fast food brands, collected each day from the chains' own ordering apps. As pricing becomes more data-driven, it exists so that customers can see what each restaurant really charges and how it compares with others nearby. It covers the US, Canada, Australia, New Zealand, the UK, Ireland, Spain, Mexico and the Netherlands. Brands are only compared with themselves, and prices are never converted between currencies.
