My inlaws recently moved to Pittsburgh, and we will be visiting from Texas over the holidays. I have never been to Pennsylvania. Obviously not looking for Mexican or barbeque. Will be with the whole gang for most meals, so not really interested in ultra fine dining, or sushi. Wanting recs for true Pittsburgh must have meals, food items, or local institution restaurants, but want to avoid the tourist traps. We will have four days so breakfast, lunch and dinner recs are all appreciated.
