Tracy Letts isn’t exactly known for comfort food. The playwright’s 1993 drama “Killer Joe’’ is about murderous trailer-park Texans - the naked (it isn’t just souls that get bared) and the dead. “August: Osage County,’’ which won the Tony Award for best play and the Pulitzer Prize for drama in 2008, serves up incest and suicide as it introduces us to another dysfunctional family, this one in Letts’s native Oklahoma.
But his latest, “Superior Donuts,’’ tries out a different recipe. Premiered in 2008 by Chicago’s Steppenwolf Theatre Company (of which Letts is a longtime member), it’s set in that city’s Uptown area, just north of Wrigley Field. The title emporium, owned by aging 1960s radical Arthur Przybyszewski (Will LeBow), is failing, but Arthur’s young assistant, Franco (Omar Robinson), thinks he can resuscitate it with healthy ingredients and poetry readings.
