It is named after its curious interior decor: a collection of soda siphons and all sorts of other bottles on display. It is a welcoming bar, open since the 1930s, which still serves up traditional tapas. Try the house specials: Callos (spicy tripe stew) and Rabo de Toro (oxtail stew). You can choose from a wide selection of wines and draught beer. It attracts a wide cross-section of the local population and enjoys an excellent reputation for good service.
