"I worked at Chuck E Cheese years ago and while the pizza was good & safe (its pretty tough to screw up pizza) but the salad bar would be a pass.
Adults and kids would just toss the tongs and spoons all over the salad bar, letting the handles fall into the food, getting all the different vegetables and dressings mixed together. All this at one of the grossest places on earth where they are putting their hands all over video games, the ball pit, pizza, and around again.
At the end of the night then we would flip all of the salad bar vegetables over into fresh containers and top them off for the next day. They did get thrown out every few days. If employees ever made ourselves a salad we would make it from the ingredients in the fridge that were not yet out on the Bacteria Bar."
those places usually have higher cleanliness ratings than your typical restaurant, especially that chinese buffet place
