Tuesday evening a small group of intermediate Spanish students will get together to share some tapas and speak in Spanish - no English - and the conversation will be led by a teacher. She'll be there to answer all of our questions and correct all of our mistakes.
I met her last week at a similar event, which I really quite enjoyed. It was very relaxed and social, but still great practice.
Anyway, the cost is just 7.50 and includes tapas and a beer. The event takes place in El Raval.
