Excellent restaurant, delicious food, options for celiacs and fast service. It's a shame that the pressure was indirectly put on by the waiters, who were rightly in a hurry to serve other tables after us and close the bill. In fact we ate in about 20 minutes...
Apart from this detail, I recommend it for both celiacs and non-celiacs and for the excellent view and proximity to the Bernina Express train station.
