The owners keep gluten free bread on hand and will substitute it to make many of the sandwiches gluten free. I tried their Naperville's Famous Reuben sandwich on gluten free bread. The owners made a point of checking to make sure the 1000 Island dressing that goes on the sandwich was gluten free too. The sandwich was delicious! I appreciate the extra measures they took to make sure it was GF. My son (who is not GF) had the Philly Cheese Steak sandwich with home fried potato chips. He said they were delicious. He liked the home baked French bread so much that I bought some to bring home for the rest of the family. We will definitely be back to dine at Ellie's Deli!
