Susannah, I could be wrong, but I think it was not so much that folks were comparing Devon's kebab places to the Original Kebabish of London *in London* as they were commenting on the relative merits of the Original Kebabish of London *in Chicago*; that is, on Devon there is a spot that purports to be an outpost of the Original in London.
Very Anglophile, and popular, Indo-Pak late night place with pictures of the Queen and Union Jack stuff on the walls. I always debate whether this is done in jest, or whether there is a special pride in being a London subcontinental, kind of like Italian-American pride of places like Brooklyn or S. Philly.
I posted a few times about the place, and I really liked the keema nan. This was a place that STP also wrote about often.
If you think of it, you might ask the folks in London if they have a shop on Devon.
