My friends and I visited Ronda from Glagsow, Scotland a couple of months ago and Casa Maria is still on my mind.
From the Catalan bread to the perfectly seared steak and fresh cooked fish, the meal was one of the best I've ever had. The service was also great - we allowed the servers to choose our food and wine, and they did so perfectly. To top the whole experience off, we left with a free bottle of wine.
If you are in Ronda you have to visit Casa Maria.
