Once again (although the last visit was almost 4 years ago) we went to Santillana del Mar for an autumn holiday; and again, we ate at Casa Cossio , three times in this particular week! The ribs were, as ever, the best I've had. but...the chicken, calamari and salads were excellent too. We also popped in just for drinks from time to time, the hot chocolate and churrios are as good as anywhere else in town. Best of all though is the excellent and truly friendly service there. We were treated like good friends rather than customers and this made the meals all the more enjoyable.More
