If you’re unfamiliar with the modern cooking of the Trás-os-Montes region, exalted by renowned Portuguese writer Miguel Torga in his book The Marvellous Kingdom, you won’t want to miss this restaurant – a fine example of honest cuisine, passion and a continued desire to improve. The G in its names is a reference to the surname Gonçalves, and the two brothers (Óscar and António) who run this eatery with its classic decor and spectacular views of the local fortress. Chestnuts, wild mushrooms, aromatic herbs, variations on the traditional Portuguese sausage (alheira), and a small cheese trolley take centre stage here, while local products are showcased on various menus with themes dedicated to the famous artists of Porto’s Fine Arts School. A tasting of Trás-os-Montes’ olive oils comes as an added surprise.
