Primanti Brothers is pronounced like this - Prih - MAN - Tee. It is not Prih - Mahn - Tee. People from Pittsburgh will take this error very seriously.
So, onto the food. The famous Primanti Brothers roast beef sandwich is a very regular sandwich with some soft fries and OK coleslaw in it. The size of the sandwich is "above average" but it is not the gargantuan monster that I was hoping to see. The roast beef is fine but it really isn't anything to write home about.
Primanti Brothers suffers from "Philly Cheesesteak Syndrome" - It is a food item that has come to represent a city's food scene and really just for tourists. It is fine food at a reasonable price but there are a hundred other, superior options.
