Yes, the fancy expensive places are great.  But more generally, I recommend that you order the dishes with game and lingonberries, most of all lingonberries.  Soups here are above average, and I do not generally love soups.  The pizza is surprisingly good, make sure you order it with "pizza salad," which turns out to be cabbage.  If you are craving non-Western food, I would try Persian before Indian or Chinese.  At breakfast, butter is consistently good.  Overall, Stockholm is a quality food city, though it is not superb when it comes to breadth.
