Operakällaren is without doubt one of Sweden's best restaurants, with history and setting to match. As the name (Opera Cellar) implies, this restaurant is located in the Opera House, which has been open for business since 1787 - although the present building was erected in 1895. The present restaurant was created in the 1960s by legendary chef Tore Wretman, who, more than any other person, is responsible for turning the Swedes into foodies. Today you'll find mouthwatering dishes such as black turbot with potato and leek purée, or roast French pigeon with hazelnuts, sweet and sour lentils and vegetable ragoût. The desserts are sublime, particularly the cloudberry gazpacho with almond milk sorbet. This is a luxury establishment on all counts - food, service and wine. And make no mistake, the prices are equally spectacular. Dress to impress.
