Restaurante O Adriano (santa Justa)
39 Calçada Carmo
A Tasca Called "O Adriano"I really like to eat in Portuguese tascas, where the food is good, cheap, and classic. And here you have a wonderful view to Rossio train station from the seats outside.
After lunch you can catch a train straight to Sintra, or you can go up Calçada do Carmo and visit Carmo Convent and Santa Justa Elevator.
Address: Calçada do Carmo, 39 (if you are at Rossio, just go to Calçada do Carmo and go up the stairs and you will see it).
