Red Robin is national chain of gourmet hamburger restaurants that uses a dedicated fryer for their bottomless french fries. Be sure to order with out the seasoning salt and mention your allergy.
I have been visiting them in Colorado for nearly three years. The staff and management have been very easy to work with. Only occasionally do I have to send back a meal.
My prefered meal has been the Guacamole Bacon Burger. I feel I get enough food for the cost (under $9).
Ordering tips: Ask for no bun. Double check that there are no hidden gluten (onion rings). No seasoning on fries. Stress the need for the dedicated frier.
A good place to eat, just be sure to state your needs with your sever. They desire to create an enjoyable dinning event.
