I'm not a fan of champagne cocktails, but it's New Year's weekend. WaPo Link. Excerpt:
The Bleu Sky
Makes 1 serving
Bartender Tim Stover of IndeBleu likes to use Gruet, a champagne from New Mexico, in this signature drink.
Pour 1/4 ounce Grand Marnier in flute, add champagne, float 1/4 ounce Blue Curacao on top.
