Salsa night at Revolucion is brought to you by Alicia Valdivia of Salsa Shanghai Studio, and is a great place for beginners to learn some new steps. The crowd gets big between 10-11pm with a healthy mix of foreigners and locals. Alicia does a quick lesson around 10.30pm, and the difficulty varies depending on who's there. The dance floor is pretty small, but a lot of people get into the dancing spirit none-the-less. Free entry, free lesson.
