Cirque du Soleil Presents Quidam

Under the grand chapiteau — a pretentious way of saying “big top” — Cirque du Soleil performs Quidam. What does Quidam mean? Who cares? There’ll be people in weird costumes flying through the air. Performances daily except Mondays, through August 6th. $28-$190. Broad Street and Washington Avenue. Times vary. 800-678-5440;
