As “China: Through the Looking Glass” comes to the end of its run, the Metropolitan Museum of Art will stay open until midnight, the New York Times reports.

The museum will be open three hours later than usual on September 4 and 5 to accommodate the steady stream of visitors to this summer’s Costume Institute show, which has already drawn more than 730,000 visitors and stands as one of the Met’s most popular shows of all time. (For comparison, the previous record-holder, the Met’s 2011 Alexander McQueen retrospective, was seen by 661, 509 people.)
