A vehicle crashed through the front of a popular Amherst restaurant Saturday night, injuring four people.
The crash occurred at about 9:30 p.m. at Cheeburger Cheeburger, 1593 Niagara Falls Blvd., Amherst police said.
The white van struck a family of three and one of the restaurant's waitresses, said Lt. Patrick Lucey.
"They were customers. They were sitting at the table and the vehicle came through the glass and pinned them against the wall," Lucey said.
Police were interviewing the elderly woman who was driving the van and her passenger.
They did not release names of the victims.
The husband, who was most seriously injured, and the waitress were taken to Millard Fillmore Suburban Hospital.
The mother and son, who is believed to be about 13 years old, were taken to Erie County Medical Center.
"The son is going to be OK. He was only grazed," Lucey said.
Irving Smith and Bonnie Kane were eating inside the restaurant at the time. There were about 15 others in the restaurant, Smith said.
"I heard the glass shatter and saw dust," said Kane, of Lackawanna. "Oh, my God, this is unbelievable to see this."
Smith said, "We were just starting to eat and talk about me pounding a burger. It blew me out of my seat."
Kane added: "Literally, he went flying."
He recovered and helped the young boy.
"I was in shock," Smith said. "It was chaos."
Police used one of their vehicles and a tow rope to pull the van out of the restaurant. Police were still at the scene late Saturday night trying to sort out what caused the driver to lose control of her vehicle.
