There's some streets with a few specific accessible spots that have signs marking them, and there a lot of parking garages around, and at least one is definitely accessible.
There is a step down in the main room to get onto the floor so the ADA section is right next to the sound booth on the raised section, about 4-6 chairs are put in this area and it isn't really blocked off, there are just some signs.
There is a balcony, and there are two staircases, but no elevators.
Available in ADA section
No there are not accessible restrooms. The ones in the main hall have a small step to get to them.
