Good way to spend a day. They have five main attractions: the chocolate tour (which is free), design your own chocolate bar, the 4D movie, the chocolate testing and the trolley ride. The design your own chocolate bar is simpler than I thought - you pick white, milk or dark chocolate, whether you want any of a few extras (chocolate chips, pretzels, etc) and whether you want sprinkles. You also can pick the design for the wrapper to the box it comes in. The rest of the time you watch the bar get built.

You buy tickets for all the attractions (except the chocolate tour) beforehand, either online or at the ticket desk inside. There are also a bunch of food options for lunch, the huge chocolate and merchandise store, the bakery, the ice cream shop and a s'more shop. The s'mores are $9 a piece, they are huge they are messy, but they are good.

Definitely either get there early (it opens at 9) or in the evening. The place starts to full up mid-day, and lines for food, treats and the chocolate tour start to get long.
