This is an old classic bar at Carrer Montcada, near to Picasso Museum with Cava tasting and good tapas.
The place is small and during the evening becomes full of locals standing next to the bar or seating at one of the small marble tables, so you might get into El Xampanyet earlier than locals, before 8.30. Sant Sadurnķ d'Anoia is a region near to Barcelona popular around the world for the Cava production, such as Codorniu, and other wines. Take the oportunity to taste them at el Xampanyet.
