The incident happened around 2 a.m. when a driver slammed into a fire hydrant on Firestone Boulevard near the restaurant.
Video from the scene shows the wreck knocked off a portion of the head off the iconic Bob's Big Boy statue outside the eatery.
The driver was pinned inside the car for a while, but was eventually extracted and taken to the hospital. Nobody else was injured.
It's not clear what caused the single-car crash.
