For a refreshing, even festive drink, there is now La Mademoiselle served in Bar Shun, the stunning new, brass-trimmed cocktail lounge across the hall from the restaurant Shun. The cocktail, created by Dushan Zaric, is grapefruit-based. To make it at home, combine 2 ounces each of pink grapefruit juice and gin, a half-ounce of simple syrup and 8 dashes of grapefruit bitters in a mixing glass, stirring over ice. Strain into an ice-filled goblet and finish with a splash of 2 ounces or so of prosecco. The garnish is a piney sprig of rosemary.

Bar Shun, 610 Lexington Avenue (53rd Street), 212-451-9228, shun-nyc.com.
