Recipe for the great Ginger Salad Dressing at Benihana: "As far as salad dressings go, this is one of the most requested, and tasty. At the Benihana chain of hibachi grill restaurants, you are served a side salad before your meal that is doused with this tangy, slightly sweet, fresh ginger dressing.
