Dining in Northeast Kingdom, Vermont
You might try the Miss Lyndon diner in Lyndonville - but if you really want to DINE, drive north a ways to North Hatley in Quebec and have a long, relaxed lunch on the terrace at the Auberge Hatley overlooking Lake Massawippi. Well worth the trip, and the lunch is a particularly good deal, given the much lower price charged for the same quality of french cuisine. They have a website but Ive not got organized to add the link here. Search and ye shall find.
There is also a well-respected patisserie in North Hatley, at the north end of the lake (there is a parking lot behind the tiny commercial area)but Ive forgotten its name. Take home a tarte tatin to enjoy later...
