Happy has made a number of adjustments since it opened in early 2009 as Happy Noodle House, most of them very smart (and earning this Big Red F venture a nod from Forbes in its "America's Best New Restaurants" lists). But none of the developments have been as happy as the evolution of the Bitter Bar, Happy's "late-night alter ego," where mixologist and partner James Lee (named one of the country's top ten mixologists by Playboy Magazine) has turned the handcrafted cocktail into a contemporary art form. At the Bitter Bar, what's old is brand-spanking-new again, as the staff gives an original twist to traditional cocktails, using local, organic, fresh ingredients — and very fresh thinking. Lee shares that thinking at regular cocktail classes that have become one of the hottest tickets in town.
