If a guest requests a mule that is not on the menu, what is the appropriate way to ring it in?

When a guest requests a mule that is not on the menu, the appropriate way to ring it in is to select the liquor that will be the base of the cocktail, specifically vodka (as the classic Moscow Mule uses vodka), and combine it with ginger beer. Additionally, garnishing the drink with lime adds a traditional touch that enhances the flavor and presentation, aligning with the expectations of a classic mule drink.

This method ensures that the guest receives a beverage that is true to the style of a mule, reflecting the characteristics of the drink they are expecting even if it’s not explicitly listed on the menu. Using a standard margarita recipe or adding tonic water would not create the desired result and would lead to an incorrect representation of the drink requested. Asking the guest for a different drink option could also be seen as dismissive, as they have already indicated a preference that should be honored if possible.
