Bifana and prego at Beira Gare: this cafeteria-restaurant, also near the Rossio metro, serves home style fast food. Their bifana (sautéed pork sandwich) was the best thing we had all week. If you eat standing at the bar, a hearty portion comes to a whopping €1.80. The pricier prego (sliced beef sandwich) was less satisfying and cost €2.20.
