I lived in East Dulwich in the late 80s and 90s and my memory is quite different. Can't remember many restaurants at all on Lordship lane besides the Curry Cabin. There were local shops like butchers, bakers, etc, but thes were all killed off when the Sainsbury's opened on Dog kennel Hill. Later, when the demographics of the area changed, these closed shops started becoming restaurants etc.

The irony is that with the increased gentrification of SE22 businesses like butchers and fish mongers are returning. So there's hope still for their return in FH.
