Mahogany Hall
From The Fifth City Wiki
"Fallen London's MOST POPULAR MUSIC-HALL presents a NEW EXTRAVAGANZA of ENTERTAINMENT each and every night!"

Mahogany Hall is London's most popular theater. It really does put on a different kind of show each day: light entertainment on Monday, circus performers on Tuesday, comedy and variety on Wednesday, opera and ballet on Thursday, singers on Friday, magicians on Saturday, and the Kashmiri Princess - Mahogany Hall's star - on Sunday. It is the center of several interesting conflicts: the Affair of the Box and the Wars of Illusion, for example.
