Hi!
I just got back, unfortunately, being there one night, it was really hard to sightsee. But, I did stop in some shops (none that were of interest to my craft) Some really gothic bars, one called Dungeon which looked very well designed like out of "Interview with the Vampire" or something. There was definitely an energy around the city though. You could feel the heavy spirituality all over! I highly suggest going for a few days!
