Polleria Fontana situated in Grácia is a place that you are unlikely to find by chance. And even if you should stumble across it it does not look like anything special except for the fact that is packed around Catalan dinner time. Polleria Fontana serves tapas the old school way so expect a greasy but delicious experience if you like these goodies just like us. I'm not a huge fan of the classic croquetes but I have to admit that the ones they serve here are really crunchy and tasty.
Also the Bomba de Barcoleneta is something you should check out. It is best described as a ball of mashed potatoes with minced meat in the center that has been on a quick trip in the deep fryer.
Basically, if you are into the classic fried tapas dishes this place is excellent and warmly recommended. However, if you are concerned about your waistline find another place. DC!
