It happened late Friday afternoon on Kildaire Farm Road between Southeast Maynard Road and Southeast Cary Parkway at the Sugar Buzz Bakery and Cafe.
The Town of Cary told ABC11 that a 77 year old man had a possible medical episode and hit the gas instead of the brakes. Officials say he hit several empty cars, and then crashed into the building.
No one was hurt.
A building inspector will check out the structure's integrity.
The driver was being evaluated on the scene.
