I just attended my second class and absolutely live it!!
I've had classes with both instructors. We tried the toning classes and boy did it work me out. I didn't feel like I was working out though. It was SO much fun. The studio itself is large and open with high ceilings, great party lighting and super fun instructors. They have a kitchenette and cold water available to re-fuel. Classes are only $10 ($5 for your first with each instructor) but can come down to $7 per class by buying a book of 20 ($140).
They also run several classes a night, every night of the week and as late as 8 pm.
The last class I did involved a mixture of Salsa, Brazilian, Indian belly dancing and African dancing in segments. A must try!!!

Approximate cost: $5-10
