I've had appetizers (including fries), pizzas, and sandwiches. I have never been glutened by any of it. Quality of GF food is good, the buns for sandwiches are especially nice (I wish they did more with them, they could totally be used for bruschetta or garlic bread, and they don't sell them separately so doing your own is out), but it's lots of very greasy choices. I am told the non-GF food is mediocre by the people I keep making get our food from there when I feel like it. One thing that's nice is I've been told that all GF orders are treated like allergen orders, as opposed to most restaurants which treat them like diet orders and you have to remember to stress your medical needs.
One thing to note: They don't allow substitutions and are really weird about any requests (difficult to even get stuff on the side), which is fine because they have a large menu so I think everyone can find something, but people with food allergies/sensitivities don't necessarily only have the one or have other food/GI issues, so it can mean a large portion of the GF menu is locked out. I'm not sure why basic substitutions, like tomato instead of bruschetta mix, are not allowed, but I assume they were getting very egregious requests at some point and just went extremely the other way.
