I know that a hall needs a stage door, but come on! This is right next to the audience entrance–ladies and gentlemen enter through the main door and the musician peasants enter through the dungeon entrance down below. This stage door looks like something out of a horror movie. Contrast this with the stage door for the Lyric Opera of Chicago, which is right on the main street level with nice doors and a lobby.
