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.
Among cities with at least 10 restaurants, Wrocław, Lower Silesian is the most expensive: its Drive Thru Index is 101, meaning its restaurants charge 1% more than their own chains' national typical prices, on average.
Next come Bydgoszcz, Kuyavian-Pomeranian (100) and Katowice, Silesian (100); the cheapest is Poznań, Greater Poland (99).
By province, West Pomeranian is the most expensive (index 102) and Silesian the cheapest (100).
Burger King's most expensive Whopper costs 25.99 zł, at the Burger King in Warsaw, Masovian: 13% above the chain's Polish median of 22.99 zł. Its most expensive basket of 6 items is 114.69 zł in Warsaw, Masovian, 12% above its median of 102.19 zł.
Pizza Hut's most expensive Margherita (medium) costs 36.99 zł, at the Pizza Hut in Janki, Masovian: 6% above the chain's Polish median of 34.99 zł. Its most expensive basket of 4 items is 180.96 zł in Janki, Masovian, 6% above its median of 169.96 zł.

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 PL, 100% of KFC locations, the biggest chain tracked there, charge within 10% of its typical Zinger Burger 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.

Methodology, about and 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 Polish złoty. The Drive Thru Index of a place averages each chain's own index there, where 100 is that chain's typical price nationally, so chains are never compared with each other; cities need at least 10 restaurants. Each chain's most expensive restaurant leaves out airports, stadiums and similar sites, which are reported separately. 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.
