Welcome to AZ.
The law regarding carry into a place that serves alcohol references an AZ statute as the enabling factor with no reference to reciprocity so, sorry, I can't help with that one. You may want to check with the local police or sheriff.
OC is available to you anywhere that is not posted or an off-limits location. OC is not uncommon in AZ so you should have few problems with LEOs.
