I shop at giant eagle regularly, and this location is the only one I will go to by default- it definitely is less than desirable.
Day or night it seems that there are never more than 2 cashiers ringing up customers. There are usually some self checkout lines available, but often times there are decent lines there too. Appears to be understaffed every time I go there.
Positives are that it is open 24 hours and they have at least 4 carts that can accommodate 2+ small children- this is a big deal! The legacy village store, which is bigger and nicer by comparison, only had 1 last time I shopped there (hence, I no longer shop there).
