In Japan, teriyaki is traditionally used to flavor grilled seafood.
In the West, teriyaki is popularly used to prepare salmon, beef, or chicken, and the ingredients in the sauce are a little different. It's also often used as a dip for potstickers. Teriyaki is meant to be a cooking sauce, not a table sauce, but it's perfectly safe to use as a dip or a condiment. Western teriyaki often doesn't contain sake, and sometimes doesn't even contain mirin, but it may include additional flavorings like minced garlic, minced ginger, or toasted sesame oil, and more sugar or other sweeteners like honey.
