I've been going to this resturant ever since it opened somoetime in the 90s. There is nothing great about this place, but the food and that is all that matters. Mehran is as close as it gets to authentic Pakistani cousine.
Another benefit besides tasty food is it is open late, very late 4-5 AM 7 days a week. Naan and Roti is made fresh no matter the time.
Draw backs, washroom are dirty and in winter place is freezing and roasting in summer, but if you ask the owner he will adjust temprature for you.
With all these flaws the food is still work it.
