Decided to visit Panda Express tonight but quickly changed our mind when we watched the cook cleaning the stove vent while they were still cooking food. My husband asked the girl at the cook line about what we were witnessing and she assured that it was fine and they did it all of the time. Now I can not say that I physically watched anything fall into the food that was being cooked but I didn't feel like finding out the hard way. Very unimpressed and won't be coming back again.
