I know I sound like a shill for this place because I do really like it, but had the chicken kati roll again today here and, I have to say, this is one of the finest sandwiches in the city. I was extremely cold and hungry, so maybe I wasn't as objective as I should have been, but I've had it before and it's always delicious.
There's something about the hand chopped meat, combined with the red onion and peppers on the griddle, all wrapped up in an extremely fresh paratha, that just works. It's one of those sandwiches where less really is more. But be warned that it's nothing like an actual kati roll—it's its own thing, but a delicious one!
