When we ate at the Sardunya restaurant last year, they came over to the table, when we were eating, and poured us some mineral water from a litre bottle, which we hadn't asked for, but for which we were later charged. We had assumed it was on the house, as other restaurants had come to the table with freebies. Yes, I know we should have asked and yes I know mistakes happen, but we were the only customers in that night, apart from a table full of their family and friends. So if going to the Sardunya, just question if something arrives, you have not ordered.
