I'm not a Spanish speaker, but welcome to the Forum and to Bern. Keep your eye on the Social Events calendar. We have a monthly dinner club that meets (English speakers, but we're a friendly lot)
So, I’m not totally sure if we can drop external links here, so my bad if I’m breaking any rules.

About Bern, I gotta say Meetup Bern is nice based on my own experience. I joined that group and met some Spanish (and not only Spanish) folks and had a good time at the events. They were really nice!
