The store is not very big, so if you go and there's a crowd expect to be up close with the other people in the pawn shop. They have a ton of jewelry, so much you might want to do a very thorough search through the cases. Most pieces of jewelry and art are for the collector, so don't expect to walk out with a cheap souvenir. If you are a fan though of the show and some of the items they collect go in - you never know what you might find.
I did find the perfect wedding band to replace the one I lost years ago (kept the husband, lost the band) and it was very reasonably priced and they soldered it to my engagement ring for free to make it look like the perfect set.
