According to Bloomberg News, the chain began offering the steak last month and continues to roll it out. The plan is to offer steak in roughly 9,600 of the chain’s 14,100-plus US restaurants.
Breakfast steak is something McDonald's has been playing around with for a while. They used to offer it on a bagel at some locations and have more recently been testing it in a few markets. It looks like the tests panned out since it's now available nationally.
