On the first floor of the popular Helvetia bar (locals simply call it Helvti) much praised chef Diego von Büren serve refined, polished versions of standard Swiss dishes. The meat loaf for example was simply excellent - it must be some subtle mix of spices that does it. For starters we can recommend the crayfish cocktail. Prices are not budget, but quite appropriate given the quality of the cooking, the white tablecloths and the exacting service.
