Great selection of GF products, mostly Schar brand. But lots of Schar products that we don't see in the U.S. Plus, wonderful cheeses, olives, prepared and raw seafood, meats, nuts, and more.
Every El Corte Ingles we have been to in Spain has a major gluten free section in their basement supermarket. It has saved us more than once to get Schar brand buns or individually wrapped packs with two pieces of bread. The Cafeteria on the top floor has a menu with all allergens listed. Not tons of gluten free options, but some is better than none!
