there is another item that i think you should definitely try out at Karim's. it is Gurda Kaleja. the dish is made of a lamb's kidneys and liver. although i acknowledge that it might be too much some some people to go to that extent, still i would strongly recommend that you try out the gravy of this delightful dish. i bet you would lick your fingers. and yes, they do not serve you only the gravy, coz its more in demand that the Gurdas and Kalejas.
