Chicago’s Victory Gardens Theater “gets pigeonholed as a ‘mom-and-pop’ operation. But now this family has a big, newly renovated house up at the historic Biograph Theater that just emptied the piggy bank by $11.7 million (and counting). And it’s facing a whole different set of economic realities. So, will the family values stay the same? Only to a point, say the parents.” One of the coming changes may be a raising of the bar for the theatre’s stable of affiliated playwrights — an ensemble whose existence sets Victory Gardens apart from most American theatres.
