This place is mandatory, especially if you want to hear some fado. Here you can listen to Fado Vadio (sung by nonprofessionals) on Mondays and Wednesdays, hear consecrated artists and potential stars, or hear a regular who just feels like singing a fado accompanied by Portuguese guitar.
Once an old tavern, A Tasca do Chico was restored in 1993; on the walls are paintings, posters, and clippings. Go early, because it can be crowded.
If you like chorizo, ask for “chouriço assado"—basically, this chorizo is on fire. Let the flame disappear and then eat it with some bread.
