We stayed at Relais Dolcevista. They do not serve dinner so we tried local restaurants the 4 nights we were in Valdobbiadene. Trattoria alla Cima was down a side road so you would not stumble upon it. We sat out in the covered terrace overlooking vineyards and hills. It was a beautiful setting and a very good meal. We were the only Americans there which was the case for most of the restaurants we tried in the area. This prosecco region is breath taking and a wonderful contrast to Venice.
We suggest you have a GPS as signage is difficult. It is a special region, not to be missed.
