Bahnhofstrasse is THE shopping street in Zurich. Running from Bahnhofplatz outside the main train station all the way to the lake, it's full of luxury shops selling designer fashion, furs, porcelain, and, of course, chocolates, clocks and watches. Halfway along is Zurich's first, biggest and best department store Jelmoli. The basement food-hall is a must. Or if you want the best in Swiss chocolate, take a break at Cafe Sprungli, the epicenter of sweet Switzerland since 1836.
Bahnhofstrasse follows the line of the moat of medieval Zurich and is mainly pedestrianized, although watch out for the trams running along it. It runs parallel to the river Limmat and it's easy to punctuate your shopping with visits to churches and other important sites of Zurich dotted in the narrow streets between. Culture and consumerism: Zurich has them both.
Bahnhofstrasse is in the heart of Zurich. The main station, Hauptbahnhoff is at one end of Bahnhofstrasse and here trains arrive from all over Zurich and Europe. The city also has an excellent tram network which converges on this central area.
