CHICAGO — There were some scary moments for diners at the popular White Palace Grill in the South Loop Saturday morning, as shots were fired inside of the diner during the breakfast hours. Luckily, no one inside was hurt.

Shortly after 6 a.m. Saturday, manager Peter Chiampas says two men who were eating inside of the diner at Roosevelt and Canal started arguing, so he told them to step outside.

That’s when he says the fight escalated, and each man pulled out a gun and started shooting at each other. Bullets shattered glass windows and tore through the building’s facade. Luckily, no one inside was hurt.

People walking by and entering the restaurant couldn’t believe what was happening.

Chiampas says even with 24 hour service and the popularity of the restaurant, he’s never been in a situation like this before.

Residents say they’re not going to let what some see as escalating gun violence across the city keep them from eating where they want to eat or change their daily routines.

While workers cleaned up the shattered glass from the front windows and taped up panes before being repairs, Chiampas says he hopes surveillance video from inside and outside of the restaurant will help police catch the shooters but he wants patrons to know “they’re open for business.”
