When Chicago’s Drury Lane Theatre opened on Michigan Ave. in 2005 it had a rocky start. Now not so much. “A lot of shows are now circling red-hot downtown Chicago looking for a venue. We don’t have enough theaters with more than 500 seats. A whole lot of in-town and out-of-town producers want a piece of Drury Lane. So does Broadway in Chicago, which would dearly love to program all the shows at the Drury Lane Water Tower and would probably do a fine job.”
