Benihana Mustard Sauce — Price, Calories, Ingredients & Recipe (2026)
Benihana Mustard Sauce — price, calories, ingredients and a copycat recipe for the creamy hibachi mustard dip.
What Is Mustard Sauce?
The third member of Benihana’s classic dipping-sauce trio, mustard sauce is creamy and tangy with a gentle horseradish-like kick. It is made from dry mustard blended with cream or mayo, vinegar and a touch of sweetness — bold enough to stand up to hibachi steak and chicken, but mellowed by its creamy base.
Like its siblings, it comes free with hibachi dinners and costs about $2.50 for extra. Mustard sauce has a devoted following: ask a Benihana regular and many will tell you it is the best of the three, especially with filet mignon.
