Had cinnamon gf scones which were great. They have fresh gf bread on Tuesdays ( which they freeze but if you call ahead they will save it fresh for you). Otherwise mostly gluten stuff which family enjoyed.
It is really not on Front Street. It is actually in the alley behind Front Street. They only have 3 gluten free selections. It is not a cafe or anything. Just a straight up bakery, so you have to take everything to go. But I have to say the cinnamon scones were excellent.
Had great options and a very sweet owner!
I didn't eat here, but a friend with non-Celuac sensitivity did. She thought the cookies were very good. It is not a dedicated gluten free bakery which is why I shied away. They do attempt to take good care in preventing cross contamination.
