The following is an article from the Guardian website and focuses on food, but many of the sites like Frommers also have walking tour suggestions.
The perfect day
Breakfast
Pick up a nüssgipfel (nutty filled pastry) from the wonderful 100-year-old Zum Brotkorb bakery, cross the bridge over the Limmat river and grab a seat at Lindenhof Square , where you can watch the old men play giant chess among the trees.
· Zum Brotkorb and Mudespacher at Markt Gasse.
Coffee with a view
The best 360-degree view in the city is from the Urania Observatory . The Jules Verne bar, directly underneath, serves great coffee. Cafe Weggen , five minutes in the other direction, is a quaint and steamy James Joyce-type of place (he holed up in Zurich to write Ulysses). It offers more varieties of hot chocolate than Starbucks does coffee (although there's one of those at Central if you're desperate). Cake does not get any better than at Confiserie Sprüngli AG Cafe .
· Urania Observatory and Jules Verne Bar, Urania Strasse. Cafe Weggen, Weggen Gasse. Confiserie Sprungli, Bahnhofstrasse 21.
Designers & lunch
Two sides of the Limmat river, two choices. For something unique head to Niederdorf . Start with the vintage clothing shops around Spital Gasse, then meander around the tiny cobbled streets filled with antique book stores and jewellery designers. Don't miss Maison Unique a homeware boutique on Froschau Gasse. Skip over Muster Brüke, turn left past Fraumünster Church and its Marc Chagall stained-glass windows, and enjoy a designer clothes fest: Jil Sander, Sergio Rossi at Willylow Shoes, Dolce and Gabbana and cult jeans at Trois Pommes . Take your lilac leather pew with the rest of the in-crowd at Piu bar and restaurant at Lichthof .
· Piu, Banhofstrasse 25. 01 225 6025.
Culture fix
There are 30-odd museums from the odd Museum of Swiss Hotels and Tourism at Trittligasse to the marvellous Kunsthaus (with Swiss art as well as Picasso, Gauguin, Van Gogh and the rest). And you could always pick up your own Warhol or Chagall from dealer Jamileh Weber.
· Kunsthaus, Heimplatz 1, open Tues-Thurs 10am-9pm. Fri-Sun until 5pm. Jamileh Weber, Waldmannstrasse 6.
Cocktail and dinner
Take the number 4 tram to Limmat Platz for Josef bar -worth the trip for the mojitos alone. You can eat here, too, but must book. If you didn't, here's where to eat. Extortionate: Kronenhalle - Zurich's answer to the Ivy but with real Picassos and Matisses on the wall. Affordable: Pizza Luigi , for the best Pizza in the city. Budget: the wurst stand at Bellevue - an institution.
· Josef, Gasometerstrasse 8 (01 271 6595). Kronehalle, Rämistrasse 4 (01 251 0256)
· Kries 6, Scheuchzerstrasse (01 362 8006). Pizza Luigi, Weinbergstrasse (01 262 33 55).
· Wurst stand, Theatre Strasse, next to Vorderer Sternen.
