This is one of the better bars along the tree lined Calle de Argumosa which in itself is full of bars. Some would be put off by the smurf blue interior but with the cool paintings and Caribbean feel I rather like it. If it’s just too much for you, you can always sit out on the terrace and watch the people go by.
The food is very reasonably priced and a little different from the typical Spanish bars. For instance English speakers would usually expect to see the Mexican chilli con carne available in Spain but this is the first place I’ve seen it. It was pretty good too.
