Zurich is a fantastic (albeit expensive) city to visit. I'm an architect so there is a lot of interesting cultural and architectural novelties going on in Zurich west. Both the old city and Zurich West have great things to offer and the city is small but very interesting and colorful.
Insider Tip:For those that dont know, compared to other metropolises in Europe, Zurich has a high cost of living, and this is reflected in the price of services (food) which is where you'll spend the most. That's the only drawback to what I find to be an excellent city with plenty to offer.
