I found this place by chance. The restaurant is very nice and has inside and outside spots. The menu is variegated, but they don't have the gluten free one. Upon request, they have a list with all the allergens. There is no gluten free beer, but you can have a good glass of wine. Always upon request you can have gluten free bread. I tried "Arroz negro de marisco con alioli suave" (for 2 persons) for the first time and I definitely recommend it if you want to try something different.
