Karachi Kitchen is my favourite Pakistani food place! This is as perfect and authentic as it gets. I only wish it was a sitdown place because having to smell the irresistible deliciousness on the way back downtown from Mississauga in the car is just torture.
They have the best Bihari kebab(marinated tender beef cooked on a charcoal flame) I've had in Canada. Amazing Biryani(rice dish with either lamb or chicken) and mouthwatering curries. AND It's cheap to boot! I ordered 2 orders of bihari kebab, 4 naans(hot from a clay oven), and 2 different types of curries( to share ofcourse) and it only came up to $30!! They cater parties as well, and you can call ahead to order for pickup.
If you are serious about your curries and kebabs and don't mind spicy food, this place is the place to go.
