A Great Victorian building, but not very accessible.
This review is especially helpful for those who have or use the following: Long Cane, Walking Aid, Wheelchair
I was there for an event that includes all abilities and disabilities and I saw some folk in wheelchairs having difficulty with narrow doorways. Other commenters have mentioned access to the toilets and the bar, I would agree with their comments.
Transport & Parking
Over a year on, Bristo Square is still a construction site. So direct access is not really possible. I don't know about any near car parking
There is a lift, but it's not that obvious as it's tucked away in a corner.
