For authentic Kashmiri food, look no further than Ahad Sons. Choose from a variety of Kashmiri Wazwan including Ghushtaba, Rista and even the Aloo Bukhara Korma.
They are willing to cater not just anywhere in the city, but anywhere in the world {provided you bear the costs, of course}. However they only cater to parties of 50 or above.
