Dear Jedx5, many restaurants will be closed on Monday, and some on Sunday as well, so do check in advance. White truffles are expensive, and very very special. Simple dishes are the best: tagliolini (home made pasta), risotto. Many restaurants will offer truffles, but the season can be a little different from one year to another. A good place is Porta Rossa : do have a look at their website (portarossa.it). It's not so "family style" anyway. Going to Eataly Lingotto, especially for lunch, could be a good idea, but if you'll want to be sure about finding truffles you'll better check before going there, and, if you go on Sunday try to avoid peak time, that is go before 12.30. In truffles season they serve good dishes, not terrible price. Look for special "truffles tables". And for dinner the elegant inside restaurant, at Eataly Lingotto, will surely propose truffles, if they are in season. Bye!
