We've been here twice, and the food has been excellent twice! They easily accommodate our food allergies, with a menu clearly marked for gluten, nuts, etc.
If you are gluten free due to allergy or celiac the Quechee Pizza Chef GF pizza is not for you. We got glutened really bad after ordering a GF pie to go. It took an hour for them to make it which seemed promising but the cross contamination was too much.
Got the shake, it tasted really good. I drink nutritional shakes often because I can't eat gluten, and this is one of the better ones I've had, I like the wide range of options and flavors too.
