We were not able to try the buffet, but made it for dinner and everything was incredible. The menu clearly labeled which items were vegan (luckily they had an English menu as were not quite able to navigate the portugese one). There were severak vegan options for every course (including dessert). The marinades on the seitan steak and kabobs were great and very flavorful. Both dishes we ordered also camed with steamed vegetables so we were able to enjoy some oil-free bites as well :). The highlight of our meal was the free appetizer which included a tofu based pesto. We ordered a spring roll appetizer which we also greatly enjoyed. After many mall veggie friendly restaurants it was a treat to see such a spacious vegetarian restaurant - a must visit if you are in Lisbon!
