I am virtually 100% certain there are no kebab houses in the City. No doubt there are plenty on the fringes of the City. - Kings Cross, Clerkenwell, Holborn, etc. In Greater London I would imagine there are literally thousands. Cypriot and Turkish restaurants tend to be in North London...
The restaurant is hard find, expect to walk between the locals' houses. It is family business located in a small room of a two floors building where the owners live upstairs.. The food is cooked on the spot, so you are sure it is fresh. ...
