Cafe del Soul seems to be a Gaudi inspired bar in Madrid, fitting as it’s on Calle de Barcelona. I say inspired by Gaudi but don’t expect too much, it is certainly no masterpiece of beauty. It has cave type seats and walls where there are very few straight lines.
The staff is friendly and it is relatively unique in a zone dominated by irish bars and tile walled Spanish bars. There are 2 entrances, one on Calle Barcelona that leads to the cave type room and one on Calle de Espoz y Mina that leads to the bar itself.
