I am a Catholic so I am going to be biased.
I went to visit on a Sunday morning, and there happened to be a Sunday mass scheduled, so I went to the mass, and then lingered a bit longer to take picture. The cathedral is built in Gothic revival style, with very elaborate decorations and tapestry on the ceiling, and multiple stained glass windows. The ones behind the Sanctuary is mind-blowing!
There are 2 small chapels, one on each side. Also, there is another stained glass window behind the choir terrace upstairs facing the Sanctuary.
Please be respectful when visiting, and it is definitely worth visiting. It is also close to Eaton Center, so you can park the car there, walk 2 blocks to visit the cathedral, then shop till you drop at Eaton Center.
