I was walking by, and tipsy me said I wanted to try it. The girl I had was named Courtney, and she was hilarious.
My first try we opened the oyster, and got a silver pearl. Which is one of the rarest colors, so I felt pretty cool. We went through all the settings. I qualified for a second free pearl, and got ANOTHER silver pearl. So, I got a matching necklace, and ring set.
I loved it, and spent about $150 in total, but it's a different experience. You get to watch them open the oyster, and they have you touch it. They clean it there.
