Mom is always right.
Years ago my mom did a tour that included the Grand Canyon, the four corners and Vegas. The trip also included a trip to the Chocolate factory. She opted to gamble the 2.5 days she was there and ditched her friends for the casino. She told me that there was nothing to see...and she's right.
For some reason I was thinking vats of chocolates pouring all over the place with workers moving the vats with a crane and mixing machines mixing chocolate.
All I saw were employees gathered around the chocolate brittle doing their thing, another group just talking and not doing anything and the machines sitting idle.
This isn't really a factory. If you blown all your money at the casino and have nothing to do than this might fill up about 5 minutes of your precious time.
This place also has a M&M store. So you can buy, you know...more chocolate.
