I'm looking to take some dance classes this summer in Geneva.

I've found a couple places (notably at Migros), but they all seem to be in French. Does anyone know anywhere to start looking?

Surprising, isn't it?

Any idea what sort of dance you want to learn? If you want to learn social dance there are a couple of instructors who know English at K'Danse. There are a couple of instructors at Tango Folies who speak English, if you want to learn Argentine tango. Many instructors in group classes do not want to spend time translating and saying everything twice. If you're serious about studying dance, you can take private lessons with an English-speaking instructor and you'll learn faster.
