I tried this place twice. It may have been recently sold, but it is a nostalgic step to an era gone by. The food was wonderful on both trips.

From there I would suggest driving to Meredith via Rt. 3...Stay off 93 and enjoy the country ride. Watch for the deer farm on the left called Bonnie Bray (sp?) farms.
