Gluten-free menu is fairly Iimited, but not a bad place to eat breakfast dinnerlunch or if you're staying nearby.
I have Celiac disease and very sensitive to gluten. I have eaten at this particular Denny's probably 10 times and never had a reaction. They do not offer a gluten free menu and the kitchen is definitely not a gluten free kitchen. Yes, I take a chance every time I go there. I always order T-Bone steak, eggs and hash browns. So far, so good.
The Denny's on the main strip (across from NY NY and Monte Carlo) has a gluten free menu and educated staff. Does not have a dedicated fryer, so nachos and fries aren't GF. It's outside of the resorts at regular Denny's prices.
