Of all the chain restaurants RedRobin probably has the most gluten free offerings. I've never gotten sick after eating here. I was very skeptical the first time I ate here and made our server ask the manager on duty and the cook to confirm GF options. Fries are done in a separate fryer and the lettuce wraps are delicious. I've had the gluten free bun once and personally didn't care for it, but I am pretty picky.
