We had some goofing around time and stopped in about 10PM. It was closed (er, what?), back at the hotel another visitor said he had brought some old knives and wanted to be on the show but was told he had to pay to get in on an episode. We never could verify if that was true or not.
Couple of days later we saw it was open and went back in, it isn't near as good as it looks on tv. The stock wasn't great, it was darker than you'd think and the cases that snake through it on tv weren't there along with anyone that is on the show.
Not really impressed in real life, might want to stick with the show IMO.
