We went because my partner is celiac, and in addition to eating, we wanted to try Asturian cider.
What a great choice! The waiter (Pedro) had outstanding service. He recommended the beef stew, and we can say that, by far, it was the tastiest thing we've eaten in Asturias. The croquettes were delicious and plentiful, and the dessert (also Pedro's recommendation) was incredibly delicious. The other guy who poured us the cider was also very friendly and a true professional.
The entire menu is gluten-free, with a huge selection of absolutely everything.
Whether you're celiac or not, I recommend this place 100%.
If we ever return to Asturias, we will definitely be back.
