I recently attended a language speed dating session organised by Franglish. http://www.london.franglish.eu/en/home They hold weekly sessions in both French and Spanish. The idea is you pair up with a native French or Spanish speaker (Spanish in my case) and speak for 7 minutes in the foreign language. This can be about anything you and your partner choose. After seven minutes you talk in English for another seven minutes. You then swap partners and the process is repeated another six or seven times.
I found this a great way to improve my conversational Spanish but I wouldn’t recommend it for a beginner; I think it would too overwhelming an experience.
