There are a lot of old-school taverns and bars in Lisbon that are tried-and-true local dining destinations. One of the most beloved is Ramiro, a traditional, no-fuss beer house from the 1950s. Since then it has maintained its reputation as the ultimate stop for fresh, simply prepared shellfish, and judging by the lines that snake out of the restaurant during peak dinner hours, everyone knows it. Favorites include grilled butterflied prawns cloaked in spiced butter, garlicky clams, and slightly sweet langoustines. It might look odd, but the crab-meat sauce served in a shell is a delicious if unexpected spread on toast. Don’t forget a bottle of crisp vinho verde, the perfect pairing for seafood.
