"I've been to Taberna Prado Negro twice and both times the women's restroom was immaculate and fully stocked with toilet paper, paper towels, and soap. And there were fresh flowers in the bathroom! To get to the bathroom, you have to pass through the small bar area, which on both of my visits was warm and scented with woodsmoke from the lighted hearth. Upstairs is a bright and spacious dining room. We had excellent service on the day we came for lunch, and the food was very good. Options are a bit limited if you're a vegetarian who doesn't eat fish (welcome to Spanish cuisine). On both visits we hiked to the restaurant from the Venta del Molinillo walking trail, but you can also drive there."
