I highly recommend it
In March of the year 2007 I went with my mother to Porto. We were wandering around the area of the university and the church that has that fantastic ceramic mural. In between all those noisy bars we found found the rests restaurant the "garden of Irene". We looked at the prices and found them to be quite good so we decided to go. We were three people in total and we ate steak with mashed chestnuts with wine and dessert for 17 euros per head, which could have cost in Madrid 3-4 times more. The service was five-star quality, I highly recommend it.
