Procópio is Lisbon's oldest still-running cocktail bar, established in 1972 and housed in a speakeasy-style venue at Alto de São Francisco with authentic 1920s Art Nouveau decor. The intimate, low-lit interior features red velvet seating and dark wood paneling, requiring a knock at the door to enter. The bar offers an extensive drinks menu including Portuguese Port, Moscatel, and signature cocktails like the namesake Procópio, complemented by a selection of tapas and reasonably priced beverages in an atmospherically historic setting.
