The Fox in St. Louis is beautiful, but it is in a dreary, almost isolated stretch, which detracts for me. In addition, there is zero slope in the humongous orchestra. I saw South Pacific a dew years back from the sixth or seventh row. I am six feet tall, yet I moved back to around the 35th row, so I could at least see something.
Boston has two. The Opera House is gorgeous, but the auditorium is a little too big. The Colonial is PERFECT, better than any theatre on Broadway IMO. Perfect size, perfect acoustics, beautiful...just a special theatre.
i agree re the Oriental in Chicago. Gorgeous. Only there once, for Wicked, and I had a seat in the 10th row or so on the aisle, so it was a perfect evenng.
The worst I have ever been to is in Richmond. They changed the name a few years back, and I think it is now the Altria, but it used to be called the Landmark. Too big, incredibly ugly, horrible side sections, acoustics that distort most of the sound and give the impression that all human voices are coming from off-stage; from the first row of the mezzanine, you feel like you are in another state.
One thing is generally true of the road theaters...virtually all of them are much too big. Three quarters of the seats are worse than anything you will get on Broadway, so far from stage.
