Playwright Ben Eisenberg sits in a Starbucks on the eve of the first rehearsal of his stage adaptation of Don Quixote. There’s just one problem it  hasn’t been written it. He hasn’t written anything in years, and his status as wunderkind playwright is quickly fading to has-been hack. His agent is apoplectic, the producers advance is long since spent and adapting a 1,000-page Renaissance adventure is beginning to feel a bit like tilting at windmills. Whether from a stroke of genius or a near-lethal dosage of caffeine and Xanax Starbucks itself begins to transform, and the errant knight arises in this delightfully theatrical and hilarious retelling of Cervantes classic tale.
