Though the "noble experiment" of Prohibition failed, other noble experiments, such as teaching horses how to shoot guns and giving suffrage to any horse that can shoot a gun, were huge successes. Celebrate the failure of the 18th Amendment with today's Groupon: for $10, you get $20 worth of sophisticated fare and old-fashioned cocktails at Gaslamp Speakeasy, located on 4th Avenue.

Gaslamp Speakeasy transports the urbane, exciting beauty of the Roaring Twenties into a modern-day hidden tavern, serving up premium cocktails, upscale eats, and live entertainment. Parched 21st-century flappers can whet their whistles with a potation from the drink menu, including a martini blended with Bombay Sapphire or Grey Goose ($12), a mint julep composed of Maker's Mark bourbon and fresh mint ($10), or a lychee martini made with crème de cassis ($13). Couple your cocktail with a choice from the food menu, whose edible enticements include gastronomic gems such as the baja shrimp cocktail ($10) and the prime-rib slider ($10). Live entertainment seven nights a week prevents distraction-craving patrons from having to stage their own shadow-puppet productions of sci-fi classics. The strict house rules forbid cell phones, standing at the bar, taking photos, and dancing the Charleston to the a cappella crooning of tablemates.
