Considering the quality of the pastry and the high standards of the locale, I would say that this is one of the best places in Uppsala for a cup of coffee and a bun/cookie/some pastry (i.e. a "fika"). For café food, however, I would go somewhere else, considering the quality and price.
Beautiful place, beautiful and gentle waitress and most of all special taste of food. We have eat a fish-soup and a green peas soup, something sweet and coffee. Very good!
