‘Pasticceria Gentile’ is probably the best “cornetto” croissant in Tarquinia if not Italy. It is an amazing breakfast if you get up early enough. It’s such a popular place that by 10am the only thing left is a crumb trail that lines the bar. The staff are great and very passionate about what they do and it is recognized in the first bite while waiting for them to make a cappuccino. I usually have to order a second because I finish it off before my cappuccino is made. The shop is just behind city hall.
