I've got an upcoming trip to visit a college buddy in Warsaw in February (see the Itineraries page for details) and I've gotten myself a 9 hour layover in Geneva. Figuring roughly 2 hours to clear customs and get downtown, plus another 2 hours or so to get back to the airport and through security, etc., I should have 4-5 hours (between 10AM and 2PM) to roam the city.

I've never been before. In fact, I've never been to Continental Europe before. Does anyone have any suggestions on how to kill a few hours in the city? The one thing I have decided on so far is to visit Cafe de Paris near the main train station downtown for I've heard is their killer entrecote. Is there anything else in that area, or convenient to it by public transport, that's a "must see"?

Also, where's the most convenient place to swap US$ for Swiss Francs?

Thanks.
