I'm a fan of the Pittsburgh Market, but I think it has a lot of room for improvement. It's a shame that it had to move b/c the new location is "meh" as far as aesthetics and arrangement go. I hope they are able to re-fashion the current location into more of a destination.
That being said it has some good options for shopping and is a great place to go to grab a local beer or some high end and locally made products. For me these are not "everyday" items, but a good spot to buy hostess gifts for when I'm traveling or to grab a growler.
There is an event space good for meetings and small parties in the back. I'd suggest looking into this if you want to support a local organization and find an affordable space to host your next event.
