We easily found Il Ceppo (even though you need to walk a short bit as the street is closed to traffic). You enter into the traditional Italian deli store and are shown downstairs into the wine shop where there are a number of tables set up for groups of two and four.
The service was outstanding and the food spectacular. We also had a glass of wine from the local wine region which was also excellent. An outstanding lunch in Vicenza.
