"Porto is still a city full of working-class eateries, locally known as tascas (or “tascos”, as local people call them). Opposite Praça de Carlos Alberto, Casa Expresso has hung on for decades serving the same dishes: rojão (chunks of pork marinated in garlic and white wine) sandwiches, beef liver with onions, deep-fried cod escabeche, and daily specials accompanied by boiled potatoes and fresh salads. Order a pitcher of the house wine to wash down your meal." - Rafael Tonon
