This has been my go-to place in the past, whenever a I visit Vegas. Since they don't serve alcohol, the dancers only need to be 18. Generally they are in the 18-21 age range.
In the past it has been a good value, but the prices are radically different from day to day, and from dancer to dancer. At times I felt like it was a great value, other times the simplest dance was going to be over $150.
