On my weekend visit to Pittsburgh, I quickly learned that Primanti Bros. was a must try.  My first taste was at PNC Park where they have an express version, but I must have had 10 to 20 people tell me that I must also try the original location in the Strip District to get the full experience.  So...at about 2am after a night of bar hopping, I wandered down through the warehouses and found myself in a packed restaurant.  I'd tried the roast beef & cheese at the ballpark and decided to try something different at this location.  I was disappointed when told that there was no more tuna, so I settled on the ham, egg & cheese.  Loaded with slaw and onions, I scarfed this monster sandwich down with ease.  Like the one at the ballpark, I found it to be good, but not great.  For me, the slaw is a bit overpowering and the soft bread makes it a huge mess to eat.  I'd order one again someday, but probably go with the black angus steak & cheese.  According to my last taxi driver, he claims that it's the best.
