This was a very very interesting experience. I do speak spanish fairly well, but didn't understand everything, and went with my mother, who speaks none. I would imagine that you have to have enough spanish to make it through a meal to survive this, however its not necessary to be fluent to find the experience excellent. The show is in complete darkness and truly demonstrates what it would be like to be blind or visually impaired. I don't want to spoil the experience, as others have said because that is part of the journey, however, with sight gone, all of the other senses are used and the theatre work, music, sound effects, and other sensory aspects are certainly something that is to be experienced to understand. Worth every penny, and definately worth your time!! Note we saw "A ciegas con luz" which is a dinner theatre experience. I would go back and see other works, but think this would be a great introduction and likely good for non spanish speakers.
