In a little town called Colle di Val’Elsa in the provincia di Siena, there is a restaurant Ristorante Officina Colle.
The food is from the local markets during the day, so the menu changes over time, and it is also local and seasonal. I want to explain the soup up there. It was a soup made of asparagus, with asparagus garnish and orange peel garnish. The black strip was made of licorice. The taste contrast was unbelievable!
If you are looking for a vegetarian- and vegan-friendly place, this is definitely it, but note that you have to ask for vegetarian or vegan items as this is not a place that is exclusively vegetarian.
via Gracco del Secco, 86 Colle di Val d’Elsa (Siena)
(it is in the Colle Bassa part, the lower part of the Colle close to the old paper factory, not in the Colle Alta, the higher part of the Colle)
