There's plenty of passing trade on foot as well as scope for car owners to stop outside for the 5 or 10 minutes they'd need to buy a few delicacies. The free and immediately accessible parking angle represents an advantage over all of London Road and half of Dartmouth Road. I imagine shop rents would be substantially cheaper here too, so attractive for the small businessperson viz. the Polish Deli on Sunderland Road.
It does take a leap of imagination though. But trhat isn't without precedent. I think most people's perceptions of Dartmouth Road have changed substantiaaly since the Dartmouth Arms was gastro-ed.
Car owners who will never know the place exists, because not much traffic passes it?
The transformation of the DA was slightly before I moved to Dartmouth Road, so I can't really comment on that. But it doesn't seem to have had much impact on the rest of the road. Boots is still awaiting the inevitable, the small shops are mostly the same as they were, apart from an interesting junk shop being replaced by an uninteresting junk mortgage outfit. And the short-lived Condom Shop. The internet cafe and the scooter shop closed down, the latter is now another lettings agent. Not much change there. I can't legislate for 'people's perceptions', but the DA (soulless, over-rated gastro-by-numbers nonsense that it is) still seems the exception rather than the rule.
