We ate here. The menu lists french fries as gluten free, but I asked the manager and he said they also fry the onion rings in that frier too. The waitress didn't really know what gluten free was.
I hate to leave this negative review. When I normally get a to-go order in the evening, the waitress and manager always double-check my order. They make sure my cheese is removed (I have a dairy allergy too.) and they remove any bread from my order.
I had a breakfast order today. I asked to have the cheese removed. Denny's used to serve gluten-free English muffins. I asked my waitress if they had any today. She replied that they did. I made my order. The cheese was on my plate and she gave me a normal English muffin. The waitress had an attitude when I politely asked her to remake my order. I also was not refunded for the gluten-free English muffin that I never received. I told the cashier what happened. She replied that they do not sell gluten-free English muffins anymore even though it was written on my receipt. I have been wheat/gluten/dairy-free for over a year and a half now. The longer I do not eat these foods, the worse my allergic reactions are when I am exposed to them. I wish the workers today took my allergies as seriously as the other workers at this establishment previously have.
