Established in 1999. What started out as a family-owned Italian restaurant has evolved into a gluten-free food haven. Vallario, who is also the chef, says his restaurant offers the largest gluten-free selection in the world. At Grandma’s Grotto, those on restricted diets or Celiac patients can indulge in deep-fried delicacies, pastas, breads and sweets — items that are usually off limits.We specialize in authentic Old-World Italian food, real New York style pizza, and delicious homemade desserts; as well as offering a full gluten-free menu. Those with Celiac disease, a digestive disorder that can develop at any point in life, react negatively to gluten, a protein that is found in foods contain- ing wheat, barley or rye, according to the National Center for Biotechnology Information. The disease cannot be cured but can be managed with dietary restrictions, which usually require the patient to cut out such items as bread, pasta and cookies. “One customer came in who was a friend of the family and she happened to be gluten free, and she brought her own bag of pasta and asked if we did anything gluten free Vallario explained.
