Flora • Oakland, CA
At Flora, a restaurant located in an Art Deco building in downtown Oakland, consultant Erik Adkins set up a classics-minded cocktail program featuring drinks like this bittersweet whiskey sour. He's also bar manager of San Francisco's ultrapopular Vietnamese restaurant Slanted Door, where he's so committed to using the best ingredients that he makes his own mixers—including eight different bitters. Here, he employs one store-bought shortcut—a dash of Angostura bitters.
