According to the Economist‘s famed Big Mac index, the most expensive spot to chow down at McDonald’s is Switzerland. While a Big Mac costs $4.20, on average, in the U.S., and as little as $2.44 in China, the famous burger runs $6.81 in Switzerland. A fast-food hamburger meal in the city of N’Djamena, Chad, meanwhile, costs roughly $25. Quick-service pizza can also cost way more outside the U.S. A Pizza Hut pie costs over $27 in Brazil — plus another $19 or so for a 2-L bottle of soda.
