Corso Italia 78, 32046 San Vito di Cadore
This is the best pastry place in the whole area, a favorite of mine is Torta di Ricotta, this is a cheese based cake that is both soft and incredibly delicate. If you are visiting in winter here you can also get an amazing hot chocolate.
Pasticceria Fiori is also renowned for their aperitivo, in which case I suggest you get either the traditional Spritz Aperol or, if you wish to try a very local twist to the spritz, get yourself a Spritz Select.

This is right next to Pasticceria Fiori, but it is a bakery which has the best pizza for take away. They also can make you sandwiches if you are about to leave for a hike.
Ristorante Bar Baita Ciastel
Via Matteo Ossi, 25, 32046 San Vito di Cadore
Here you can have a very simple, yet delicious, traditional meal. The restaurant is very family friendly and the prices are low.
I would suggest you try Cervo (it's deer).
Malga Rin Bianco
Via Monte Piana, 35, 32041 Misurina
While you go here you will have an amazing view of the Tre Cime di Lavaredo. The cousine is traditional and the portions are on the large side. If I were to suggest you a dish to try it would be Casunziei all'Ampezzana, this is pasta which is filled with beetroot, you can have it only in this area of Italy as it is typical from this province.
