The good: it's a decent but not great workout and the cost is reasonable relative to competitors in town and other major cities.
The bad: some of the instructors lack the certain joie de vivre of the more established barre workouts (like Dailey Method and Bar Method - neither of which exists in Vegas, unfortunately). The class times also leave a lot to be desired. No morning classes during the week except at 10am (except 7am on Wed) and no midday classes either. Meh.
The ugly: It's rare that instructors engage in corrections or offer modifications. This is especially frustrating to see when people who are new to the barre workout start out. Frankly, it's dangerous.
