They (Broadway, Bangor) have a nutritional menu, with gluten items in it. You have to be very clear with the person taking your order. I'm super sensitive, and never gotten sick, but was given gluten 3 out of 30 times going, this was 5 years ago. I told them the errors of their ways, no problem since. Orono location, different story.
They don't have a gluten free menu from what I've seen and I wouldn't really trust ordering from here given all the gluten foods they have.
They said they had a GF menu, but couldn't find it. It would not be my first choice, but we ate there. I had salmon and mashed potatoes and felt fine.
