When I moved to the area over 30 years ago now, there were not so many places to eat on Lordship Lane. There were the curry houses - long may they remain - Le Chardon, The Savarin (?) and Never on a Sunday (Greek), though there may have been others I've forgotten. Then gradually shops that sold other merchandise were turned into restaurants, reflecting I guess both increased disposable income and women not being expected to cook in the evenings on their return from work. The point I'm trying to make is that inexpensive places to eat are/ were not replaced by expensive places to eat, more there is a growth in the number of restaurants on Lordship Lane which reflects changing times and tastes and not just the changing demographic of East Dulwich.
