I've recently taken a pre-beginners set of classes at YoYoEast, at the east end of the Beaches (so, no comparisons to other studios are available or made). I was very pleased with the class - the facility was simple but pleasant enough and the instructor was very attentive to the limitations of each of the students. The only drawback is that it's the last store before the streetcar turnabout and the squeal as the streetcars make a sharp turn can sometimes be a bit distracting. Looking forward to continuing on with some evening and weekend classes.
