We visited here last year and this was the first place that my wife wanted to eat this time around. And we weren't disappointed! It is an excellent location right on the prom - so, if you select your table judiciously, you can watch everyone wandering along - high fashion to beachwear, you'll see it all.
As for the food and service, it's really been said already. The staff are well trained and enjoy looking after you; the food is of the highest quality. My wife's starter of prawn ceviche thai style and salmon tartare with avocado was superb and my calves liver simply melted in my mouth. We raved about those two dishes so much that, before we came home, we made a second visit and ordered them again - but this time I had the fish and she had the liver.
Somehow I can see us visiting again next time we get to Marbella.
