Having married into a family from Spain a few years ago (and traveling to Spain twice before that), I can say with certainty that Costa del Sol is one of the most authentic Spanish restaurant you will find anywhere. I had previously thought other "tapas" restaurants were truly Spanish but I now know that most are just a mix of different Latin/South American/Spanish foods. Costa del Sol is owned by a Spanish family, the food is absolutely out of this world, and the service impeccable! If you want to travel to Spain for an evening, without the cost of a plane ticket, head to Costa del Sol! Highly recommend!!
