Time Out says
Enjoy a quality meat-free meal
That rarity of rarities, a decent vegetarian (and vegan) restaurant deep in tourist central, Bistro Artha makes best use of its location – close to Poreč city market. The menu has plenty of options without forcing you to resort to pizza, and whatever you choose – pasta with truffles in a creamy sauce, say – you can accompany it with a tasty, fresh salad. The desserts are top-quality too, and a handy carrot to have if you’re persuading the kids not to have hamburgers or chicken for once. Management puts a lot of love into the place, and it shows. Hibernates from December until March.
