Police are investigating a Thursday morning break-in at American Coney Island on Lafayette Boulevard in downtown Detroit.
Owner Grace Keros said the incident happened at around 5:30 a.m.
"They broke in the door and stole an empty register," she said. "We are cleaning up and getting a new door. We are open."
The broken door is on the Lafayette side of the building.
It appears there were two suspects, said Cpl. Dan Donakowski, media relations officer for the Detroit Police Department.
The incident is being investigated and police are looking at video footage from the area.
Donakowski said the American Coney Island break-in may be associated with a couple of other break-ins that occurred in that area sometime overnight.
American Coney Island helms the triangular corner of Lafayette and Michigan Avenue. It was founded in 1917 by Gust Keros, a Greek immigrant, who created the famous chili dog.
Next door to American is Lafayette Coney Island, another iconic coney spot. The two are long-time rivals and debates often take place about which is better.
But earlier this month, Lafayette was ordered to shut down by the City of Detroit Health Department's food safety division because rats were seen in the restaurant. Lafayette remains closed for cleaning.
