I regret that it is no longer possible for my wife and me to dine at Primanti's on Friday evenings.  The crowd is too enormous and the lack of reservations or phone-ahead seating causes the diner to have to wait a long period of time in a loud, congested waiting area.  Additionally, there is not adequate parking to accommodate the hordes, thus the diner may be riding round for a long time in order to find a space.  Many park in spaces that were not designed to accommodate vehicles, and which make it difficult to navigate through the narrow passages.  I will have to find another time to dine at one of my favorite spots.  Weekend nights at the dinner hour are out.
