Hello Pittsburgh experts. My daughter will be starting at Duquesne in a few weeks. We've only been to Pittsburgh once to view the college, so when we come down to move her in mid-August, we'd like to see more of your city. We'll be staying at the Doubletree Hotel & Suites/Pittsburgh Center. Our last stay there was great, and we walked between the hotel and the Benedum Center area where we shopped, ate, and went to a play. Other than that, we've only seen Duquesne. We enjoy just walking around shopping, stopping for drink/food, viewing historical/architectural sights. Are there any "neighborhoods" that we should spend time in, or is the Pittsburgh Center area the main spot for that? Any restaurant suggestions would be appreciated--nothing too expensive ($35+ for entree) or jacket-required. Thanks for any suggestions.
