The chain has a policy of serving only two alcoholic beverages per adult, but an Inside Edition investigation revealed the policy is not well-enforced.
For 40 years, Chuck E. Cheese’s restaurants have been thrilling children by serving up pizza, arcade games, and amusement rides at more than 550 family-friendly centers around the world.

But it isn't always fun and games as some children’s parties have turned into battlegrounds thanks to adults behaving badly.
There have been violent brawls at Chuck E. Cheese’s across the country with some resulting in calls to the police to break it up.
In Parma, Ohio, police say a mob of customers stormed the kitchen and attacked Chuck E. Cheese’s employees.
In Miami, all hell broke loose as customers slugged it out with each other.
In Manchester, Connecticut, patron Lamar Wallace took out his cell phone when he saw customers climbing tables and throwing fists in the middle of the Chuck E. Cheese's where his young niece was having her birthday party.
“When I saw this happening, I was like, 'Oh my god, is this really happening with kids around at Chuck E. Cheese?'" he told Inside Edition. "I couldn't believe my eyes."
A possible culprit for the violence may be the fact that alcohol is served to adults at many of the restaurants.
"This is an atmosphere that is chaotic," Parenting expert Dr. Gayle Lewis told Inside Edition. "Children are running around screaming — add alcohol into the picture — I think that just adds to the stress and adds to the capacity to act out.”
She added: “While I don't think it's the only thing that contributes to these fights, I think it's an element if removed could diminish the amount of fights that could happen."
The restaurant chain has a policy of serving only two alcoholic beverages per adult.
Despite the rule, an Inside Edition producer had no trouble ordering four glasses of wine at one Chuck E. Cheese’s location on New York’s Long Island.
Inside Edition's Chief Investigative Correspondent Lisa Guerrero attended a child’s birthday party at a different Long Island location about 20 miles away, where she was informed of the two-drink policy after ordering a couple of beers.
However, a server informed Guerrero that if she provided someone else’s ID, she would be able to order two more drinks with no problem.
"So as long as somebody else gives you their ID, then you can still order more?" Guerrero confirmed.
"Yes," the server responded.
“We know you have a policy of only serving two alcoholic beverages per adult but I was able to order four today," Guerrero told the manager.
“I'll give you the number you guys can call,” the manager replied, referring Guerrero to the corporate office.

In a statement, Chuck E. Cheese Entertainment told Inside Edition that they take their alcohol policy very seriously and, “after a full investigation, we determined that employees failed to follow our alcohol service procedure."
They added that "maintaining a safe experience” for children and their families is of "utmost importance to them."
