Mayor Bill de Blasio and other city officials cut the ribbon to kick off grand opening performances that will include Impractical Jokers, Sting and Peter Gabriel, and the Beach Boys. The new venue incorporates the historic Childs Building, fully renovated, that will house a restaurant and the box office.
