Kitchen in NW is fine. Facing North is fine while coking the food.
Cooking person in the Kitchen should be facing either the East or the North Direction.
If the cooking slab is in the East to West Direction, the Sink should be on the East end of the slab and the cooking oven should be in the middle or the west end of the slab.
Shelf to keep utensils should be in the west end of the cooking slab.
Shelf to keep cookware, groceries etc, it should be on the back side of the cooking person/South wall of the Kitchen.
