Have a close friend with Celiac's who spends lots of time with us in Lakes Region in the summer. You can find a GF menu at Fratello's

Also, if you happen to be in Tilton area, Unos and 99 have GF menus.
In Meredith, I am pretty sure that Guisseppe's serves some GF, as I recall one of our dinners there they even had a GF chocolate dessert special.
Agree with Patrick's recommendation - 2 thumbs up for GF offerings!
