Not gonna lie, I don't think anyone in this restaurant actually understands what gluten is...BUT the foods are so simple that I felt safer here than some other places in San Juan. It's oysters and simple seafood dishes like ceviche, and the main sources of gluten are bread and chips served as sides, (you can request that dishes be served without). It's definitely not ideal, but since options in San Juan aren't plentiful and I managed to not get sick here, I would cautiously recommend.
