A Yakiniku Restaurant is a Japanese style of cooking (though it is original from Korea) and its main characteristic is that you are able to grill raw thin slices of meat (usually beef) and vegetables over a electric/gas grill placed in your table.

It is also known as Japanese Barbecue.
When the ingredients are cooked you can dip them in a sauce known as Tare.
This sauce is made with soy sauce, sake, mirin, sugar, garlic, fruit juice and sesame.
