The thing about ZRH is that the airport itself is not very big. I mean it did take a tram about 5 minutes to get me out to the plane but there aren't a ton of flights. BUT it sits on top of a huge train station and shopping complex that took me a couple of visits to figure out. Shopping, restaurants and a place called The Circle. There ARE luggage lockers in the train station.

And here is the website for the airport itself. If you see daylight you are in the airport. If you are underground, it's the train station/shopping complex.

You CAN catch a train into the City Center but if you are just looking for a way to walk around and have a meal, seriously, the train station has it all (except for some nice architecture).

Here are the restaurants and shops in "The Circle" which you can walk to:

Also, the Swiss lounge IS very nice!
