What to Do? What to Do?

Tonight, director Barry Levinson and cast members celebrate the 30th anniversary of Diner at Hopkins' Shriver Hall. Levinson and crew will discuss the iconic film, after a screening of Diner and Diner Guys. Jazz fans have a tough decision to make: Warren Wolf at An die Musik or Peabody's Latin Jazz Ensemble, led by Tim Murphy, at the conservatory's East Hall. Howard Alden and Jeanne Gies bring their "Tis the Season" holiday show to the Cabaret at Germano's, and Ultra Nate's Deep Sugar presents "A Tribe Called House" at Paradox.

Tomorrow, Arty Hill, Paul Margolis, and John Shock play Roots Cafe—the brainchild of Baltimore contributor Geoff Himes—at An die Musik. And Kal talks political cartoons at the Walters, at 2 pm, and signs copies of his 2012 calendar.

If you haven't seen American Buffalo at Centerstage, this is your last chance—it closes this weekend. David Mamet's writing is brutally rhythmic, Liesl Tommy's direction is crisp, and the acting is uniformly superb, especially William Hill (playing Don), an actor you might know from HBO's Boardwalk Empire.

And The Lion King returns to the Hippodrome for a five-week run.
