Heyho Nice that a community is starting thank you for your thread start. I traveled a few Weeks trough Italy on Keto the country of Pasta and Pizza…
My tips for eating in a restaurant go for steak or bun less burger, often they had in Italy a starter plate with cheese and some meat like salami and bacon or some cold thin meat peace’s forgot the name. I also can recommend mozzarella with tomato’s. If you need something on the go, cheese cubes also salami and nuts were a good snack.
Go for it and just try it works with a little effort also on a trip.
