"Made with 100 percent real cheese," a McDonald's advertisement said.
There was something missing in some of McDonald's new mozzarella sticks — cheese.
In a statement to WMAQ, the company apologized for the awkward slip up.
It said, in part: "We are aware of a low volume of guest concerns about our Mozzarella Cheese Sticks. ... We believe the cheese melted out during the baking process in our kitchens and shouldn't have been served."
McDonald's said it was fixing the problem.
One customer told Newsy the company sent her free coupons for new mozzarella sticks. Hopefully they have cheese in them this time around.
