How do you not love this place and give it at least 4 stars? It's Free and at the end of the self guided tour, they give you samples. I mean, what place in Vegas give you freebies without extorting your personal information or harass you for money?
I know this place isn't like See's candy where you can get to a bite of what you want for free but it does come close. Lots of Visitors from buses get dropped off here so make sure you make it in line before they do!
The Cactus garden is just as short as the self guided tour. There are drinks for sale towards the end of the tour as well (Which makes perfect sense for having eating sweets along the way).
A Must visit when you're in the Henderson area.
