This isn't spelled the same as Al Qaeda, so I have no idea what that part of the sign means. I wasn't able to determine in the 30 seconds that I tried whether there are various spellings of the name of the organization.
I am pretty sure they had that name well before Al Qaeda. Was just still a bit odd they hadn't bothered changing name at the time given the similarities.
The sign has however since been taken down and the shop rebranded.
We do however still have an Isis Cafe .... named after the Egyptian goddess. Need to remember to go take a pic of their signboard.
