Steps from the madness of Gran Via, is the cute, cozy café Celicioso. Not only are all of their products 100 percent gluten free, they are insanely delicious! They serve a variety of cakes, cupcakes, breads and other sweets to savor at the café or to take home. One of my faves is the amazingly moist chocolate cake with raspberry glaze!
While you can find a couple other gluten free bakeries in Madrid, Celicioso is by far the best. They have the best variety, a super central location and seriously awesome pastries. I don't follow a gluten free diet, but I still hit up Celicioso often!
