THE Boom Boom Room is no longer. The majestic 18th-floor bar in Andre Balazs‘ Standard Hotel over the High Line will be changing its name to QT after receiving a cease-and-desist letter from a San Francisco music venue of the same name. “We didn’t realize how many Boom Boom Rooms were out there,” a hotel insider tells BlackBook magazine’s Steve Lewis. QT was also the name of Balazs’ hotel in Times Square, although he has since sold the property.
