Share your hotspots in Zurich!! :)

Hi All,
I'm staying in Zurich from Friday - Sunday, probably on my own, and I am an out of towner (yes I'm living in Basel) I was wondering where to go to in Zurich?
Looking for some nice places to have a casual meal, then some bars where it's not weird to see a 30-something show up by herself, and if you have tips for nightlife I will definitely consider :).

What would be great is to get a feel of the real Zurich and not just the generic stuff you find on the internet.

All help is welcome!!!!
Cheers
Patricia
