I happened to pass by this small bar while waiting for a tour. The staff, one lady, was so friendly. She made me the best porchetta panini on focaccia bread. Added fresh mozzarella, cherry tomatoes, lettuce. Toasted it just perfectly. The best thing I have had in a week in Italy. 7 euros plus whatever the Coke was. Excellent value in a city of tourist mediocrity....,wine, cheese and salami, too. Restaurant next door looked great, too.
