The practice of teppanyaki and barbecue is ever-changing, and each has its own advantages. The main difference is that the ingredients directly contact the fire during barbecue, while the teppanyaki ingredients contact the iron plate, adding a layer of medium. Charcoal is generally used for barbecue, and it will taste like charcoal. Personally, I prefer barbecue. Teppanyaki usually uses more oil in order not to stick to the iron plate, and I seldom eat it in order to lose weight. Many ingredients are better cooked with iron plates than barbecued. For example, I like to fry black eggs with iron plates, which is impossible for barbecue.
