The crown jewel of any trip to Pittsburgh. It had been four long years since my last Primanti sandwich...worse than forty years in the desert.
My friends visited here three times in 24 hours. Arriving a few hours after them, I only made it two times. But thanks to a local Yelp thread, I was able to move our last two trips to the Strip location--open 24 hours! (And trust me, it's a much different crowd on Sunday at 2pm than Sunday at 2am.) Plus it's the original, so there is history here. But in the end, it's all about the food.
Thanks to that thread, we put egg on some of the sandwiches from trip #3 and tried some of the recommended meats--capicola and corned beef. All was great advice. Before I got there, they were ordering turkey and cheesesteak (both got thumbs-down from the thread posters).
Yes, this location is a little grungy (the restrooms are dreadful). Yes, it is cash-only. Yes, it is usually full or overflowing. And yes, the waitress was surly. So what? It's one of the best sandwiches that you will ever eat in your life. And six bucks is a steal. I would pay double.
