Even though I don't speak French, I was able to participate in their Sunday afternoon class. I was recommended to this spot, and later found out it's attached to a Vedante Center. The vibe was kind of like Baha'i center; there was a cooking class and it smelt scrumptious, a kid's yoga class has just finished so there were people of all ages. The instructor demonstrated to the class what she wanted us to do, and would quietly explain finer points in English to me by the mat, which was loaned to me and all the props I needed. Occasionally she interjected English into the class, and was incredibly gentle.
Très bene!
Addendum; on their schedule, they list when they have bilingual/English classes. I went back to their open class (bilingual) and left with my body purring like a well loved cat
