ST. CHARLES, Ill. (CBS) — A St. Charles official says it’s not clear yet when a familiar downtown restaurant can reopen – after the building’s second floor fell a foot and a half two days ago.

As WBBM Newsradio’s Steve Miller reports, nobody was inside the Szechwan Restaurant, at 117 W. Main St. in St. Charles, when two columns gave way and the floor sank 18 inches late Monday.

Why did it collapse? Was it the age of the building, or heavy rain from the spring and summer? The anser remains unknown, says Bob Vann, Building and Code Enforcement Manager for St. Charles.

“There’s a lot of speculation going around, obviously, but they just want to stabilize the building,” Vann said.

And the Szechwan Restaurant itself on the second floor? It’s not clear when it can reopen.

What about one of the restaurant’s attractions – its large aquarium?

“The fish are OK,” Vann said. “The aquarium is tilted, obviously, but the fish are still swimming.”
