Of the Giant Eagle branches I've been to around town, this one is the cleanest (with two sets of well-maintained bathrooms!) as well as the best organized. The store is quite large, and they tend to have a variety of brands available for each type of product. I also love that they have a selection of organic, speciality, and ethnic products. The staff is friendly and helpful if you ask them a question. And finally, there's tons of parking!
Great supermarket if you are in the area!
