This is a small place (22 seats) in the Barrio Alto, at no. 46 Rua do Norte at the corner of Travessa da Espera. The exterior has no sign and is covered with graffiti (photo 1). We stepped in with trepidation and came out with bliss. They have a clam dish with coriander, onion, mustard, garlic, and butter which is extremely good (photo 2). There was also a breaded fried whole whiting that was very tasty (photo 3). We had lunch and came back for dinner a few days later, about 20 minutes before opening, and joined a line of about 12 French tourists. The dinner was not quite as good - nothing special about the grouper. The house white wine, Alentessano "Alto Alentejo" was delicious. The interior was a bit crowded but pleasant (photo 4). There was still a line outside when we left. Lunch was €38, dinner €47.
