Creekside Co-op at 7909 High School Road, Elkins Park, Pennsylvania.

I'm part of this co-op, so let that stands as a disclaimer. I come here primarily for a particular brand of local coffee that supports women growers and the restoration of trafficked women, and anything else is icing on the cake. The pastries here are great. The produce is good, I believe, but may be expensive if organic. I also appreciate the number of small or local brands available.
This morning they had an Irish breakfast for St Patrick's Day, and live music in the cafe. Had I time (and neither dogs nor groceries in the car) I might have sat down for a coffee and a listen.
There were high hopes for the co-op early in, and I don't think all have been fulfilled, but the local grocery is helpful in a suburban town center, and it's become a "third place" on its own for various activities.
