The halwa puri with channa is really good. Kinda like of Shaheen. And yes, these two places only serve the authentic karachi style 'lahori' cholay for breakfast. The nihari was a little watererd down but full of flavour. The fresh naans was the icing on the cake. Their 'chai' needs to be overhauled. I have had better tea at gas stations.
I highly recommend the halwa puri channa breakfast. But please, take home-brewed chai in a thermos to enjoy the meal.
