Website tracks fast food prices every day to help you find cheapest places to eat

The price of your favorite food order could be completely different depending on which restaurant you visit, and one website is tracking just how much chains charge across the world. Called Drive Thru Index, the site collects menu prices from thousands of locations belonging to major chains, including McDonald's, Burger King, KFC, Taco Bell, and Wendy's. It updates its database daily using prices listed on official restaurant ordering apps, revealing how the same items can cost significantly more or less depending on where they're sold. There's also a daily blog documenting price changes across the United States.
