Lunch Near Vinci
Unfortunately, there aren't a ton of options in Vinci. Avoid anything in the main piazza in the lower part of town, there is a pizzeria that takes forever to serve you.
Up the hill there is both Ristorante Leonardo and La Torretta near the museum. Neither is exceptional, both are OK. La Torretta has a lot of salumi and prosciutto options as an appetizer, if you like that. Ristorante Leonardo is a dark family run place, some decent pastas.
