Hands down the worst service I've ever had at a restaurant.
My friend and I were in town for the weekend, so we had to hit up Primanti's. I lived in the 'burgh for about three years, and have had it before (from the dahn-tahn location) but my friend hadn't.
We came in at 1pm on a Sunday, certainly not busy at all. We sat at a table by the bar for about 15 minutes being ignored until we got fed up and sat at the bar instead.
My friend and I ordered a sandwich each and I asked for no cole slaw. Seeing as how I'm pretty sure that these sandwiches are not pre-made, I didn't think it was a big deal. The waitress stared blankly at the ceiling and replied "I'll see what I can do." Eventually, our food got there and it was okay, not the greatness I had built up to my friend.
It took about 20 minutes for the waitress to bring the tab after asking for it (I almost thought about committing my first dine and ditch out of mercy). We had to flag down a different waitress to take our money. For the first time in my life, I left no tip.
