French courses (Jakarta)

Hi all,

I'm working at Accor Asia Pacific. It's a french company that handles Pullman, Sofitel, Novotel, Mercure, and all Ibis.

I was wondering if anyone knows a good weekend french language class? I need to brush up on my french as it's been years since I actually used it. I want to be considered for a transfer in the main office in Paris.. and to do this you have to be fluent.

Any ideas?
