McDonalds testing three types of Big Macs

McDonald’s is testing some massive changes to its popular Big Mac. The chain is testing a “Grand Mac” and a “Mac Jr” that will appeal to different customers with smaller and bigger appetites.

The “Grand Mac” has a third pound more beef than the regular Big Mac and, an extra slice of cheese, and a larger bun, Columbus Business First reports.

The Mac Jr. is a single-patty burger meant to be eaten on the go.

The burgers are being tested through June 6 at hundreds of restaurants in central Ohio and the Dallas/Ft. Worth areas.

A McDonald’s franchise owner also revealed on Tuesday that they are building the “McDonald’s of the future” which includes all-you-can-eat french fries, a massive play area for kids, and kiosk ordering that allows customers to create the exact burgers and chicken sandwiches they want to eat.

The new 6,000 square-foot McDonald’s will even offer table service and employ 85 workers to assist customers with all of their needs.
