Strip, South Side and Station Square are the tourist traps. Nice enough places, but aren’t remotely the best places in town. If you are a tourist these places are going to be confortable places to visit, and worth seeing.
However there is a lot more to Pittsburgh than these same old 3 areas that get all the press.
I love the strip district for three coffee shops I found. La Prima is really good, and a lot less than starbucks!
