After “more than a decade of dreaming and planning, having the dreams fall through, regrouping and planning again,” a new $52.7 million, 1,500-seat downtown theater for Chicago’s mid-size performing arts groups is almost ready to open. There are some worries, though: “With costs of approximately $4,000 a day, it is far more expensive than the theaters previously used by many of its dozen founding members. With 1,500 seats, it is also larger, and groups may find themselves lost on the larger stage or have trouble filling the extra seats.”
