The showstopper in bartending is, without a doubt, fire. The classic drink for this purpose is the Blue Blazer, which is simply Scotch and water tossed back and forth in a flaming arc between cups. Impressive, but not quite ideal for brunch. And perhaps you don’t want to dim the lights and drag out the chafing dish required for a Café Brûlot Diabolique. The Café Royale is your single-serving recourse.
