The La Favorita restaurant in Madrid has been fined 12,000 € by the City Hall for refusing to serve a gay wedding party, according to the El Mundo newspaper today. The council considers that the establishment has committed a ‘serious infraction’ and been guilty of discrimination.

The owners have denied discrimination and say they will appeal the decision.
The fine imposed can range between 3,000 and 15,000 €.

The married couple say they don’t want the matter to reach the courts as it could affect the workers at the restaurant, who they say are not to blame.
