Angry customers at Bacci Pizzeria on Clark Street near Wrigley Field threw punches and physically attacked each other.
"I just saw people yelling, they started pushing. One guy picked another guy up and slammed him on the floor. They started fighting and throwing chairs. Guys were punching girls and girls were punching guys. People getting smacked with heels in the face, it was crazy," said Luis Reyes, Bacci delivery driver.
Reyes witnessed the brawl storming through the restaurant. He says what began as a war of words over cutting in line to order pizzas quickly turned into a fist fight. It lasted a few minutes and eventually inched outside the pizza place. Witnesses say a girl was hit with a Hennessey bottle and knocked out.
"And knocked her out completely. The pounding kept coming from heels, left and right.. The back of the heels stabbing her face," Reyes said.
Officially, investigators are only saying that two young women apparently started the fight and two other 24-year old women were injured and treated for "minor injuries."
Witnesses say it was a booze-fueled fight that put plenty of people in danger. In just seconds, people waiting for pizza started pummeling each other in a fight that spilled out onto the streets just steps from Wrigley Field. It started with a simple shove and quickly became a melee involving about a dozen people.
"I was going to tell them to get out and don't argue but once started slamming each other on the floor and swinging I just let them go - let 'em fight," he said.
Chicago police are investigating the fight, but no one has been arrested or charged. Witnesses say it was worse than that when the fight spilled onto Clark Street.
"When they knocked her on the floor, they hit her with a Hennessy bottle and knocked her out and then kept pounding with their heels - the back of their heels, just stabbing," Reyes said.
Doorman Nate Gill works next door and says, in a different incident, he too was attacked by women wielding shoes.
"She knocked a girl down in front of me and I tried to shield her to protect the girl and she proceeded to take off her stiletto boots and started swinging!" Gill said.
"If they can't act civil when they're drunk or control themselves then they shouldn't really drink," Reyes said.
A top aide to Wrigleyville Alderman Tom Tunney says the area has not seen an increase in problems on the streets. In fact, police recently re-tooled safety and security deployments in the neighborhood but security inside businesses is the responsibility of the owner.
