We took a chance having been tipped off by our Napa wine tour guide. As you can't book, it could be a bit hit and miss, but we waited less than 5 minutes on a Saturday night to get a table for four. Tables were constantly full, with locals as well as tourists and the place had a warm atmosphere. The food is standard Italian fayre, but all well cooked and served by friendly staff. The wine list isn't extensive, but covers most tastes and budgets. A welcoming place in an upmarket area of town.
