A man drove his Toyota right into the front entrance of the business on Leffingwell Avenue at approximately 2:30 a.m.
Inspectors were on scene to try and determine if the building was structurally sound.
Gregory Brooks, who works in the building, said he and his co-worker were stunned by the impact.
"It sounded like a train went through the building. I mean, it really shook," described Brooks. "We went out the side and came through the side door, we saw that there was a tail end of a car. So right away, I went to call 911 and my co-worker went to see if the driver was OK."
Fortunately, no one was hurt - not even the driver.
"The guy looked like he was drunk. He really didn't say anything. I believe he was still shocked," Brooks said.
The driver was arrested for suspicion of driving under the influence. His identity was not immediately released.
