A massive fight broke out at a Chuck E. Cheese location while kids ran for safety.

We're not sure what caused the brawl, but this was ugly. If there's one place where things like this shouldn't happen, it's Chuck E. Cheese.

An entire family got into it with another family or other patrons in the the entertainment venue and much of it was caught on camera.

We hope these "Adults" learn a lesson here, that this type behavior is NEVER cool---especially when kids are present.
