what in the world is this?--on youtube search for chinese fried rice--you will see a cook using a grill that has a stainless vent like attachment on grill apx 6 inches by 3 feet by 5 inches high with numerous slits on it. he is reaching over it to fry some eggs. Any idea what this is?--Looks like a vent to me but why in the front instead of the back. If so what if any are the advantages or disadvantages--if yu cannot find it i have a photo of it- and can post to flickr if needed
