Looking to make friends in Lille

Hi there, I'm new in Lille and I don't know anyone here yet! :(

I commute to Lille for work so I'm not usually around on weekends but it would be nice to meet up with people for lunch or an after-work drink. I'd love to meet some fellow expats, especially if we can get a language exchange going too! (I speak French and English, obviously, but would like to improve my Spanish, German, Italian, Polish, Dutch and Mandarin in particular, although really I'll happily learn a bit of any language!)
