This Lisbon landmark has been selling Portuguese wine since 1927 and is easily the best spot to pick up a bevy of local wines and spirits. It is especially helpful and will steer you towards lesser-known boutique wines and vintage ports in addition to the usual suspects. The small museum features vintages dating to the 18th century.
There are other outlets in the Mercado da Ribeira and at Rua da Conceição 20/26 in Baixa.
