Got upcharged $10 for a substitution. Paid $22.50 for a dry overcooked Impossible burger. It was just a miscommunication but when I brought it up the person who seemed to be the manager only defended the price and said the owner docks their pay if they mess up. This is the main reason for my 1 star.
I had ordered the cubamati before and got the Impossible burger instead of tofu for a small upcharge. In passing, the server quickly told me it would be $10. I thought he meant just $10 for the sandwich, but he meant for an upcharge in addition to the $10 sandwich. The cheese is $2.50 extra too, which was sparsely sprinkled and not melted. They were also very understaffed and my dry burger got cold while I waited for much needed water. We spent $65 and I'm disappointed to say that we won't be going back. There's too many better vegan options in the area. Also, the manager weirdly said our server was the only vegan they hired, like that somehow had anything to do with their policies, the understaffing, or the poor cooking of the burger. This was not his fault. It was a joint miscommunication that happen while I was chasing my toddler back from the bathroom.
I was planning on bringing my whole family there for these iconic Pittsburgh style sandwiches, but not at that price and quality.
