Are you talking about Kakao Chocolate factory in Cozumel? If you are, we did this last year and it was great.
We were there for 2 hours. We watched a movie on how the cocoa beans are collected and then we made our
own chocolate that we were able to take with us and we got to sample about 15 different types of chocolates
that they make there. There were 4 of us and the cab ride each way was $5. You don't want to walk there...
