Chipotle is a go to place for our family when we want something we can be sure is gluten free. Although it seems small the selection is perfect. You don't get distracted by too many menu choices.
My daughter, who has celiac, really loves the rice so we just get her a massive amount of that. The rest of us, depends on the day and mood. I can honestly say, though, I've only been disappointed that I've never had enough room in my stomach to eat it all!
