Guys in flip-flops hang at the bar next to distinguished couples in tuxedos and evening gowns. The location of the Absinthe is perfect for a drink before a night at the San Francisco Opera and at the Davies Symphony Hall. And the drinks have what it takes—the barkeepers even wrote a book about that. The lively mood is contagious and makes you think of a Paris bistro. Adam Keough’s Francophile cuisine with classics such as onion soup or spicy rabbit meatballs adds to the ambience.
