There are three theaters in the complex and during the summer, there is something playing nearly every night. The Shakespeare Festival's shows in the summer are outdoors and consistently good. The smallish theater in the round facility produces some of the most engaging productions, because of the intimacy. There are no bad seats in any of the venues.
Plan for a pre- or post- show snack or meal at the nearby Prado Restaurant. It's only steps away in the park and is a terrific place for a meal in the restaurant proper or something simpler in the bar.
