The cocktail cognoscenti decry this disco-era original as helping bring about the dark ages of imbibing – that 30-year period when Old Fashioneds gave way to Appletinis. They're absolutely right. But who the hell cares when it's Sunday morning, your head's pounding, and the smell of shame and regret is seeping from your pores? The Harvey Wallbanger wakes up the dreadfully boring Screwdriver with a float of herbaceous Galliano — that towering, svelte bottle collecting dust on the backbar. The OJ and vodka provide the vitamin C the body craves after a rough night and the booze needed to short-term-fix that headache. But the anise-laden and faintly vanilla-y liqueur actually gives it some flavor. Replace the vodka with aquavit for a much improved caraway complement.
