By Serena Maria Daniels | The owner of a longtime improv theater in Wrigleyville told about 100 supporters Sunday night that she needs their help to fight a large hotel and residential development that she says threatens the future of her establishment.

A packed audience listened to pleas from iO Theater owner and director Charna Halpern and others as they described how a strip of Clark Street, a mainstay for Cubs fans to barhop after ballgames, will dramatically change if the complex is built at Clark and Addison streets.
