Japanese love beef tongue. However, it is eaten almost solely as Japanese BBQ or stewed. Japanese like deep fried food but Japanese do not come up with an idea to wrap with breadcrumbs and fry it.
Then, beef tongue is extremely popular when ordering at Japanese BBQ restaurants. You can find dozens of meat on the menu card but nearly every table orders beef tongue at least once.
Then, beef tongue was be eaten first, before eating other parts of beef meat. On the other hand, it is not common to order it again during the lunch or dinner. Also it is nice to eaten with lemon sauce rather than soy sauce based sweeten sauce.
