It's only okay. I compare this to the sandwich juggernaut that is Melt Bar & Grill and it falls short on all accounts. However, as a casual sandwich place, it's not terrible.
Portions - average. I can finish the whole sandwich in one sitting.
Creativity - not too many options to choose from. The fries being INSIDE the sandwich turns them soggy and flavorless.
Taste - very mediocre. Cole slaw is one of my favorite sides and it was bland and too vinegary. The bread they use is not grilled or buttered or anything. Weak.
My husband originally raved about this place being so filling and just what he needed. Later on he tried Melt and forgot about this place entirely. I asked him again what he thought of Primanti's and he chalked up his initial reaction to not having a sandwich in a long time. At the time, it hit the spot.
