The male pedestrian was fine after being clipped by the Mercedes when it careened across the sidewalk and then broke into the seating area of Francesca's Brick Oven Pizza in the borough's main business district on Rock Road around 1 p.m.
Both he and the driver refused further medical attention after being evaluated by EMS.
"The 76-year-old driver was attempting to park in the angled parking spots near the front of Francesca’s [when he] hit the gas pedal instead of the brake," Lt. Frank Riggio said.
The business sustained damage to its front window pane and some of the facade.
No one inside was injured.
The Mercedes, which bore a handicapped placard, was removed by a flatbed tow truck.
Responders included Glen Rock police and firefighters, Fair Lawn police and a Hackensack University Medical Center ambulance.
