Amazing restaurant with great vegetarian options! A bit on the pricey side, but if you just buy one…read moremeal, you can manage (if you're not too hungry, and don't order drinks and extras)!
I got what I believe is a vegetarian version of a Sardegnian pasta dish, "Maccarone de busa con crema agli aromi di Sardegna).
The pasta was al denter, not too soft, and the sauce was incredibly creamy which I loved. They serve it in a "fancy" bowl that looks like you are not getting a lot of food, but the portion size is okay if you're not too hungry.
15 euros is pricey...but if you really want to try Sardegnian food made vegetarian, this is a great option.
