DaTerra has been my favorite Porto area restaurant. Technically in Matosinhos, DaTerra is a fantastic vegan and vegetarian restaurant. Matosinhos is known for its accessible beaches. I recommend seeing the beach before eating at DaTerra. If you're like me you'll eat so much you couldn't fathom walking more than 100 meters. Similar views pictured below await you in Matosinhos.
Porto Aerials Workshop. Do you see the first well lit white space on the left hand side? That area features select merchandise that I think are made by local artisans. Everything is very clean here, the staff is efficient, the colors simple.
Waitstaff will come over eventually, like the green polo shirt attired gentleman, to see if you'd like a drink. Otherwise, you can order drinks and desserts at the counter located to the right of the picture. Once you're finished eating, you will also pay at the counter.
If you visit Porto, go to DaTerra especially if you're a vegetarian or vegan.
Final note: Most of my vegetarian restaurant experience has come via the Mercury Cafe in Denver, CO. Comparisons arise as a result. If you like cheesecake, don't order the Merc's "cheese"cake. All you can taste is the soy unless it's covered in a fruit compote. DaTerra's tofu desserts taste like fruit and keep their structure. The Merc's cooked vegetables can range from mushy to hard in one dish. DaTerra's mixed vegetable dishes retain their consistency. The Merc's design seemingly revels in chaos. DaTerra features simple lines and cleanliness. The Merc's waitstaff is inefficient. You might feel ignored at times. It's not just you. DaTerra's staff is accessible and friendly even if you butcher Portuguese words.
