The New Britain Diner on Corbin Avenue was forced to close Saturday night when a car crashed into the building.
The New Britain fire department said a car was turning into the diner parking lot from Corbin Avenue when it was rear-ended by another vehicle. The force of the impact sent the front car into the building.
The driver of the second vehicle was taken to the hospital for treatment of minor injuries. No one in the other car or the restaurant reported injuries.
The diner had to close until officials determined if the building was structurally safe.
A diner employee confirmed they would remain closed until Monday morning at 8 a.m.
