As of my recent visit to South Hills Village I noticed that they are trying to get a little more upscale with the addition of Michael Kors next to the Coach store. They are also building a 2nd restaurant in the food court area that has something to do with noodles.
I think they are trying to add a few of the businesses that are in Ross Park Mall but really don't have the room for all of them. The only good thing about that is saving the long drive to the North Hills from Upper St Clair.
For me driving to the mall isn't hard since I know back roads that save me time off of Washington Road.
Best time to go is early morning when it opens or during the dinner hour. Again try to avoid Sat as it does get crowded. Jared is also located in the complex but as a stand alone store along with Barnes and Noble and Bone Fish grill.
