I think you guys get Indian food mixed up with pakistani/afghani foods. Nan and chicken tika are really afghani in origin, while sweets like jalapi and other stuff are indian. Most Indian places serve piss poor nan and chicken tika, unless they're owned by kashmiris or punjabis. I know they all seem the same, but most Indians do not make good biriani and other stuff because it's not really their type of food. And paki places suck at making sweets. You're not gonna get good everything in one specific place.
calmus, jalapi will make you fatter than onlyme.
