5. Casa Mariol

After you have toured the Sagrada Família, head away from the throngs to this quiet café and vermouth bar just a five-minute walk away. The restaurant is owned by Casa Mariol vineyard (located in Catalonia's Terra Alta region) and one corner is devoted to barrels of their wine and vermouth. You'll see a steady stream of locals coming in to fill bottles and exchange neighborhood gossip with the proprietor.

Order: Pair a glass of the house vermut negre with olives stuffed with mussels and slices of fresh-made coca topped with sardines and roasted red and green peppers.

Address: 442 Carrer del Rosselló, casamariol.com
