I think the people who were behind the objections are still not going there - they're not Nandos peopel anyway.But Stokey has more than one community and in reality Nandos was introduced to target the contingent that isnt particularly interested in keeping things independent. KFC on the High Street thrives too, remember.
The difference is that Nando's is on Church Street, and there are no other chains on Church Street other than the recentish addition of Wholefoods. Church Street is the symbol of trendiness and that well known Stokey thing, whereas the High Street is almost seen as an extension of Dalston which until fairly lately hasn't been trendy. So, KFC is okay because it's on the High Street, Nandos is not because it's on Church Street: it's like stabby a yuppy in the heard as opposed to kicking him in the shins.
