Gluten free options but cross contamination can happen (check with each location)!! Red Robin has an allergen menu that shows you what’s safe to eat and what’s not. My boyfriend has celiac disease and has ordered a burger with gluten free buns and french fries, as well as their cauliflower crust pizza without any reaction! I would be careful about cross contamination and check with the staff before ordering to be safe!

Had the Salmon Sandwich and it was delicious and so happy to find a gluten free bun and a tasty one at that too- would love to know where to get some? Fries and tots were perfectly crispy and flavorful. Would visit again.

I looove this Ruby's! The wait staff and really everyone is so welcoming, and they always remember me and ask how I'm doing. The food is the best American comfort food you'll find and it's very reasonably priced, with huge portions! I'm addicted to the dark chocolate chip shake, it's a problem :) They also have gluten free hamburger buns and English muffins which is the reason I first became a customer, and now I'm definitely a regular!

Pretty good and much improved over prior restaurant. Gluten free pizza was great and service was excellent.
