This Giant Eagle is the store I typically stop at for Starbucks during the work day, simply put, because it is closer to work than to the Starbucks store.
This Giant Eagle Starbucks is slow and typically under-staffed. Additionally, the structure for paying with your Starbucks card is a pain in the tuchas. I'm not really sure who's fault this is, the Bird's or the Bux, but the employees manually have to punch in your card to a special "card-reader" instead of scanning your card like they do at the regular stores or even at the Target Starbucks. While this isn't the fault of the employees, it does add to the slowness of the service.
I can't speak to much more of this Bird location than the Bux. I have taken a stroll around this location and they have a larger prepared food section than some and the store appears clean. I'd probably be more inclined to shop the Bird if my local store was this size and nice. This location also sports a Get Go which is a perk for those of you using Get Go points.
All in all I'd probably give this a 2.5 out of 5.
