I went here with some non-veggie friends so that everyone would be happy with the choices on the menu. We paid 10 euros a head for a main course and unlimited sangria. It was fine and we enjoyed the sangria but the food was a little boring and basically seemed like re-heated canteen food. It came out very quickly. My veggie meal was a soya steak (obviously shop bought and just heated up) with cream sauce and rice and chips. Basic fast food really. The service was good and our waitress was really friendly but for the price and quality there are plenty of better (veggie) places to go in Lisbon.
Cons: Not much choice, Not great quality food
