If you are happy to drive about 45 minutes - an hour out of Zurich, there is a mountain called Santis Der Berg. I was there last weekend with a few friends, and if the weather is good, the view from the top of the mountain is beautiful.

There is also a restaurant for lunch etc afterwards at the bottom. You can walk the second half (instead of the cable car) although I think at this time it will be snowed out. 

This is the link to the website:

depends what you're looking for in terms of bars and restaurants. for climbing there's also an indoor place you can go to if Sarah's place is snowed out:
