I think someone already suggested it but an excellent location for a Dominoes would be the empty Angle Bar on corner of Brockley Rise and South Circular - plenty of room for bikes and ideal as a take-away/delivery service I would have thought.
I was told that the flat occupants above the Angle Bar premises complained, when it was an Indian restaurant, about the strong odours from the extractor fans. The council sided with the flats. So the restaurant stopped cooking food and became a (short-lived) bar. Makes me wonder why the council gave planning permission in the first place.
If Dominos were to move there, I would expect similiar objections.
