My husband and I are dropping our twins off in Pittsburgh to visit friends at Carnegie Mellon the weekend after July 4th. The two of us would like to really experience some Pittsburgh dining.....near the historic strip if possible, as that is where we are staying. We live in NYC and are not so much into 5 star dining as we are interested in eating, well, Pittsburgh. When we went to Philadelphia, we did the cheese steak thing and found a culinary school/restaurant that was fabulous. Any suggestions for the two of us, please?
