The Osteria dell'Enoteca is a little bistro and a kind of wine bar. We enjoyed both in our lunch visit. I had a nice glass of Orvieto Classico, and Mark had a Russo (a generic, tasty red). For lunch Mark had linguine with truffles, and I had polenta with goat cheese and truffles. The food was wonderful, some of the best that we had during 18 days in Italy, and we ended up buying a bottle of the Russo wine. The ambience is very cozy, and the restaurant is located very close to the Duomo in Spoleto on a quiet street.
The restaurant has a website, with English, at http://www.osteriadellenoteca.com/.
