At intermission, D.C.-area theatergoers usually dash for one of two places: the restroom or the concession line. If you’ve been up since 6 a.m. running the country, it may take a jolt to get through three more acts of Henry IV. The Folger Shakespeare Library understands that a need for caffeine is no disrespect for the Bard and offers the best theatrical coffee experience around. Two lines form in Folger’s Great Hall at intermission: one for general concessions, and one just for coffee and tea. The volunteer servers may lack the chutzpah and cleavage of Mistress Quickly, but they smile and take your $2 and hand you a cup. In comparison to the Folger’s fresh-brewed Peet’s Mr. Dickason’s Blend, other theaters’ offerings taste like burnt overpriced Starbucks (ahem, Kennedy Center) or, well, Folger’s from a can (ahem, Atlas Performing Arts Center). Drink up! And, thanks to the short coffee line, you may have time to hit the restroom before returning to the theater, fired up and ready for another hour of Elizabethan wit.
