You would likely have to rent the dungeon for that purpose.
As far as I know there are no photos allowed except for in specific areas. However sending an email to the venue might produce a more definite answer.
No cameras or recording devices are allowed in the back area at all.
Contact the venue owners, if your will I g to support the facility(hook them up financially, etc. I'm pretty sure& confident that you could set up a photo-shoot. As long as it's not during an event & or with people from said event without their consent, their shouldn't be an issue. Ultimately though, it's up to them, the owners.(Theresa, Kronos)
From what I remember there are days where organized photo shoots do occur there. If you contact one of the event organizers they might be able to help you a little bit better
