We were staying in Coin over Christmas 2013 and this restaurant was recommended by our hosts. It has the reputation as being the best restuarant in Coin, and being the holiday season we wondered if we would be able to get a reservation. We opted for lunch rather than dinner and were not disappointed. I had the Hungarian goulash and my wife had fish. Both dishes were excellent even if they were not traditionally Spanish!
The restaurant is very simple, almost like eating in someone's front room. The service was very good, attentive but not overbearing.
We will certainly try this restaurant again and have no hesitation in recommending it to others.
