After being diagnosed with celiac, a friend told me that surprisingly Red Robin does a great job with gluten free. And they do!!
There is a gluten free menu, which describes what alterations are made to make the meal gluten free - including gluten free buns. The restaurant in Redmond has a separate work area, and my meal comes out on a plate, rather than the typical basket. We were told that the fries are prepared in their own fryer, so no worries of cross contamination. All servers seem to be well aware of what they need to do - and we even noticed on the bill, my meal has an "allergy alert" next to it.
We are so impressed - we've even signed up for the Red Robin card - which let's us earn burgers. I hadn't been to Red Robin since my kids were young - now they're grown, but my husband ( non-celiac) and I are regulars there!
