Meh.
I hate to say it, but this place has already seen better days and it really isn't that old. There's nothing terribly special about it. A vast majority of the establishments are chain stores/restaurants. And with so many great unique eateries in Pittsburgh, it's not really special to go here for a meal. A lot of small chain retailers have already left the site. The big box stores are fine, but they are in every strip mall in America. The apartments there seem to be on an island between a walking path and a 6 lane highway. This was one of the first brownfield rebuilds in the area and it's a good lesson of how not to go about building out a rare waterfront parcel of land. Yes the parking is free, but I'd rather pay a few bucks to park and shop at the unique shops in Shadyside, Downtown, or the Southside. Plus the food is astronomically better at the these other locations. For the big box stuff... It's a one stop shop, but a lot of that can be found cheaper on-line anyway. The best thing about the place is the COSTCO!
The three stars I gave can be awarded this way: One star for attempting to redevelop a brownfield, one star for putting a Costco there, and one star for NOT putting a Walmart!
