It's official! After a successful test run in Dallas and Ohio earlier in the year McDonald's plans to roll out changes to the iconic Big Mac in 2017. New ways for Big Mac lovers to enjoy this popular burger staple!

In 2017, for a limited time, McDonald's will be rolling out a bigger and smaller version of the Big Mac called "Grand Mac" and "Mac Jr.".

The "Mac Jr." will have one burger patty and one bread slice taken away while the "Grand Mac" has 66% more beef, an extra slice of cheese, and a larger bun. Both will still have "all-beef patties, special sauce, lettuce, cheese, pickles, onions – on a sesame seed bun".

If you are lucky enough to live in Florida and Pittsburgh you'll have them on your menus in November. Everyone else will have to wait until 2017. McDonald's is hoping new burgers will attract new customers and this may very well work!

And, who can forget this iconic Bic Mac commercial from 1975? It was so hard to get the jingle out of your head!
