Upon further investigation I have asked my sister about her eating experience in Spain, by no means a reliable source when it comes to food. Nonetheless.
She said the one that really traumatized her was during her visit to Granada, where she hiked up a mountain for a couple of hours, and was starving by the time she reached the top. Ended up eating here: http://miradordemorayma.com/
Asked for the special, which was leg of lamb. Basically got served a massive hunk of meat with absolutely no flavour. Inedible. Said the view made up for it at least.
She speaks highly of this place: https://www.tripadvisor.in/Restaurant_Review-g187443-d2067276-Reviews-Duo_Tapas-Seville_Province_of_Seville_Andalucia.html
