Arguably the best, or at least one of the top contenders, for restaurants in Kinosaki, this place serves absolutely incredible Tajima beef dishes. They're so good, they're worth making a trip to Kinosaki just for them!
You can reserve (and you totally should) a table only for the evening. You cannot reserve a table during lunch hours.
The photo showcases the "Tajima Beef Steak Set of the Day" I had, and let me tell you, it was phenomenal.
