Cheap places to eat out in London

No worries. I'm a bit of an evangelist for the place because it's awesome but not very busy, and I desperately don't want it to close down.

Especially this bit:

I hesitate to use the word "ugly" to describe a section of the city that many thousands of people live in and may very well be quite fond of, but my God, Camberwell is not a pretty place.

...ten minutes walk from Camberwell Green and hiding in the windswept forecourt of the most intimidating concrete atrocity you can possibly imagine, there's Zeret Kitchen. "This had better be good", we thought, as we shuffled past iron-shuttered cafes and boarded up shops towards it.
