Not recommended at all, they have two restaurants we went because they had gluten-free food, in one of them they treated us very well and there was a variety for celiacs. The next day we went to the largest restaurant because there were more of us and it was disastrous, the food was scarce, expensive and poorly prepared, the service was unprofessional, read the reviews otherwise you will be very disappointed!!
At the Origen restaurant they made patatas bravas for people with celiac disease (they can use sunflower oil). Find out before offering this type of food. There was no favorable treatment, only that they were kind and more professional (they invited us to a dessert and there were 5 of us) but we still appreciated it. Admit your mistakes, the food was scarce and expensive. You just have to see the reviews, gentlemen, that's what they are for.
