3Designated driver? Going back to work after lunch? Having a party with lots of teens and tweens or people who just don't want alcohol? When a cocktail isn't the right choice, it's time to enjoy a mocktail: delectable, refreshing soda- and juice-based blends that forgo the alcohol but keep the flavor. And there's more than a standard-issue Virgin Mary or a Shirley Temple on the menu here. Kester Thompson, a top bartender, understands that you can't just forget the tequila in the margarita or the rum in the daiquiri; the flavor won't be right that way. Instead, he's whipped up a host of gourmet sensations, some meant for a sophisticated palate, others designed to please a thirsty child.
