This might not be for everyone in this group but I organise Salsa classes and socials around London and we have a special promotion until the end of Feb at one of my Club, The Boston on Tuesdays:
So why not take this chance to learn Salsa :)
The venue has a lovely floor, very cheap bar (we were having Irish Car Bombs last week... good times) and a nice seating area for chatting and meeting each other.
If it is your first time just quote "Meetup.com" for a free taster class and entry for the night :)
If you are free do come along,
