I have not gone, but there is an open "square" next to the Starbucks where they set up bands on Thursday nights. From pictures I have seen it looks like the crowd flows over into the area in front of the Movie theater. You can check out the music schedule at the North Hills

You can see some pictures and videos of what it looks like at the north hills "buzz" website
