Should I wear a dress?

I have been looking around for an "intercambio" which is like a social language exchange for a while and the most popular one in Madrid happens every Thursday night at Cafe Madrid in Opera.

However when I found their website I must confess I thought I had stumbled on something else.

I'm not sure they really thought that URL through. I only came here to learn a new language doctor!
