They had a live guitarist/singer, and he was amazing.
Launched into a Flamenco style song that he later told me he composed, that was incredible, his fingers were literally flying all over the fretboard of his guitar!
And this was accompanied by a great meal of scallops grilled cheese, jumbo prawns and skirt steak, with a Serrano pepper Margarita in a courtyard setting with an illuminated fountain in the middle.
I still get goosebumps thinking about it!
Must visit this place when in La Paz
