This small, intimate theater seats 450, which makes it a nice space for really seeing the plays presented here. For more than 35 years, this professional, non-profit theater company has filled its seasons with quality performances, often written by talented young American and English playwrights. The theater's season starts in April or May, just as the Seattle Repertory Theater season comes to an end and it runs through November. Many patrons are regulars who have had season tickets for years. These diehards are conspicuous by the "ACT" stickers on their windshields.
